Your brain is not broken. That's the first thing worth saying. Anxiety is the most common mental health experience among young people in the UK — the NHS Mental Health of Children and Young People Survey (2023) found that one in four young people aged 17 to 22 met the criteria for a mental health condition, with anxiety and depression the most common by a significant margin. If you lie awake replaying conversations, feel sick every morning before school, or spend whole days convinced that something bad is about to happen: you are not unusual. You are not weak. You have a brain that is working very hard at entirely the wrong things.

Here's what's actually happening in there.

The alarm that won't turn off

Deep inside your brain sits a structure called the amygdala. Its entire job is to detect threats and trigger a response. When it senses danger, it fires a cascade of stress hormones — mainly cortisol and adrenaline — that flood your body within milliseconds. Heart rate spikes. Muscles tense. Breathing quickens. Digestion slows. Your body is physically preparing to run or fight.

This response evolved to deal with real physical danger, like a predator. It's brilliant for that. The problem is that the amygdala cannot reliably tell the difference between a predator and a difficult social situation, an exam, or a text you've been waiting two days to receive. It treats all of them as threats and fires off the same alarm — with the same physical consequences.

In teenagers specifically, this system is even more reactive. Your prefrontal cortex — the part of the brain responsible for putting things in perspective and saying "actually, this probably isn't that bad" — isn't fully developed until around age 25. Right now, in your brain, the alarm system is working faster than the off switch. That's not a personal failing. It's neuroscience.

Things that make anxiety worse without you realising

• Your phone at night. Blue light from screens delays melatonin production, which pushes back sleep onset. Poor sleep raises cortisol levels the next day, which makes the amygdala more reactive to everything. It's a loop: anxiety disrupts sleep, poor sleep amplifies anxiety.
• Avoiding whatever makes you anxious. Avoidance feels like relief, and in the moment it is. But every time you sidestep something difficult, your brain records it as "we escaped the danger," which confirms to the amygdala that the threat was real. Avoidance makes anxiety grow over time, not shrink.
• Caffeine and energy drinks. Caffeine directly stimulates adrenaline production. If you're already running on a heightened stress response, you're essentially adding fuel.
• Scrolling right before sleep. Social media keeps the brain's threat-detection system mildly engaged — comparisons, bad news, the general low-level stress of other people's lives. It prevents the wind-down the nervous system needs.

What actually works

These aren't folk remedies or positive thinking. They're techniques drawn from Cognitive Behavioural Therapy (CBT), which is what NICE — the body that decides what the NHS recommends — has endorsed for anxiety in young people based on decades of clinical research.

• The 5-4-3-2-1 grounding technique. Name five things you can see, four you can physically feel, three you can hear, two you can smell, one you can taste. It sounds deceptively simple, but it forces the brain out of the catastrophising loop and into the present — where there usually is no actual predator.
• Write the thought down and then challenge it. CBT is largely built on the idea that anxious thoughts are predictions, not facts. Get the thought onto paper. Then ask: "What is the actual evidence this is true?" and "What is the most realistic outcome?" Most catastrophic predictions, when written out and interrogated, don't hold up under questioning.
• Gradual exposure. The opposite of avoidance. Whatever situation makes you anxious — build up to it in small steps. The amygdala un-learns "this is dangerous" by accumulating evidence that you survived it. This doesn't mean throwing yourself in the deep end; it means the smallest step that makes you uncomfortable, then the next one.
• Exercise. This has more evidence behind it than many medications. Aerobic exercise — running, cycling, swimming — reduces cortisol and increases endorphins. Three 30-minute sessions a week produces measurable reductions in anxiety symptoms. NHS guidance says so.
• Sleep. Seven to nine hours is not aspirational for teenagers — it's biological. A sleep-deprived amygdala is measurably more reactive to stressors than a rested one. Sleep is not optional if you want the other techniques to work.

When self-help isn't enough

If anxiety is affecting your daily life — keeping you from school, stopping you seeing friends, making eating or sleeping difficult — for more than a few weeks, it's worth talking to someone professionally. Start with your GP; they can refer you to CAMHS (Child and Adolescent Mental Health Services) or, in some areas, a school-based counsellor.

If you don't want to wait, Kooth (kooth.com) is a free, NHS-commissioned online support service for young people under 25 — no GP referral, no waiting list, available evenings and weekends. Most secondary schools in England also have a counsellor you can see without telling your parents first — ask at the school office.

This page isn't going to lecture you. It isn't going to tell you that what you're doing is wrong or try to scare you into stopping. If you're reading this because you've been hurting yourself — or you're thinking about it — then you're already doing something right: you're looking for information. That matters.

Roughly one in six young people in England aged 16 to 25 have self-harmed at some point (NHS Mental Health of Children and Young People Survey, 2020). That's not a statistic to make you feel like it doesn't matter — it's there so you know this is not some dark, shameful secret only you have. It's something a lot of people deal with, mostly in silence, and mostly alone. You don't have to be alone with it.

What self-harm actually is

Self-harm usually means hurting your body on purpose as a way of coping with overwhelming emotions. Cutting is the most common form, but it also includes burning, scratching, hitting yourself, pulling hair, or restricting food. What makes it "self-harm" isn't the specific act — it's that it's happening as a response to something internal, something that feels unmanageable.

It is not the same as a suicide attempt. Most people who self-harm are not trying to die — they're trying to survive something that feels too big. That's an important distinction, though it doesn't mean it's something to brush off. It's a signal that whatever you're carrying has got too heavy to carry alone.

It is not attention-seeking. That phrase gets thrown around and it's both unkind and inaccurate. Even when self-harm does become visible to others, that's usually because the person needs someone to notice they're not okay. Wanting someone to notice is not something to be ashamed of.

Why it works — and why that's the problem

Self-harm works, in the short term. Most articles about this don't say that plainly enough, but it's true and you probably already know it. Physical pain can briefly block out emotional pain — it shifts the brain's attention, produces adrenaline, or creates a feeling of control when everything else feels chaotic. The nervous system is genuinely responding.

This isn't a failure or a weakness. It's just how brains work. You found something that takes the edge off, and the brain did what brains do — sought relief. The goal, eventually, is to find something else that does the same job without the damage.

Things that can help right now

These aren't substitutes for proper support. But if you're in that moment and looking for something to try first:

• The 5-4-3-2-1 grounding technique. Name five things you can see, four you can physically touch and feel, three things you can hear, two you can smell, one you can taste. It forces the brain out of the spiral and into the present moment — which is usually, in reality, survivable. Keep going through the list until the sharpest part of the urge eases.
• The delay technique. Set a timer for 15 minutes and make a deal with yourself — if you still want to after the timer, you can. Often the sharpest peak of the urge passes within that window, and after 15 minutes you can reset the timer again. Many people find they can keep stepping it back until the moment has passed entirely.
• Write it or draw it. Not to share. Just to get it out. Some people find externalising the feeling — even scribbling something on paper — lowers the internal pressure enough to let the urge pass.
• Intense exercise. A run, press-ups, something physical. It releases adrenaline in a different direction and can shift how you feel faster than you'd expect.
• Box breathing. In for 4 counts, hold for 4, out for 4, hold for 4. Repeat four times. This directly activates the nervous system's calming response and takes around 90 seconds to work.

How to tell someone

This is usually the hardest part. Most people worry about the reaction — that whoever they tell will panic, overreact, or make everything worse. Those fears make sense. But keeping it completely private tends to become its own burden over time, and for most people, having someone else know is a relief — even when it doesn't feel that way beforehand.

You don't have to start face-to-face. Childline (0800 1111) is free, available every day and night, and their counsellors have had this conversation thousands of times. They will not be shocked, and they will not automatically call your parents or the police unless they believe you're in immediate serious danger. Online chat is available at childline.org.uk if speaking feels too hard.

If you want to tell someone in your life — a friend, a parent, a teacher — you don't have to do it perfectly. You can show them this page. You can write a note. You can say "I've been struggling and I wanted you to know." That's a sufficient start.

Getting longer-term support

Self-harm itself isn't usually what gets treated — it's the thing underneath it. Your GP can refer you to CAMHS (Child and Adolescent Mental Health Services) for talking therapy. CBT (cognitive behavioural therapy) has strong evidence for helping with the anxiety, depression, or trauma that often sits below self-harm.

Waiting lists for CAMHS are long in many parts of England right now. If you're waiting, Kooth (kooth.com) is a free, NHS-commissioned online mental health platform for under-25s — no GP referral needed, no waiting list. You can also text SHOUT to 85258 for free 24/7 crisis support by text, any time.

In 2021, a former Facebook data scientist named Frances Haugen leaked thousands of internal company documents. Among them was research that Instagram's own teams had conducted, which found the platform worsened body image in teenage girls — and that the company knew this and continued anyway. This wasn't a conspiracy theory or media speculation. It was Facebook's internal data, in their own words.

That's a useful place to start, because the conversation about social media and mental health often gets framed as "is it good or bad?" The more accurate framing is: these platforms are built by engineers, using behavioural psychology, to keep you on them as long as possible. Understanding how that works is the first step to using them on your own terms.

How the engagement machine works

The core mechanism is variable reward — the same psychological principle behind slot machines. B.F. Skinner demonstrated in the 1950s that unpredictable rewards (sometimes you get something good, sometimes you don't) produce more compulsive behaviour than reliable ones. The pull-to-refresh gesture is a slot machine lever. The notification badge is an unpredictable reward. Likes appearing in batches — something researchers have documented — is deliberate, not accidental.

Tristan Harris, a former design ethicist at Google, spent years documenting how these techniques work. His testimony to the US Senate in 2017 and the documentary The Social Dilemma (2020) detail specifically how notification timing, infinite scroll, and autoplay are engineered to override your intention to stop. You're not weak for finding it hard to put down. You're up against teams of engineers whose job metric is time-on-platform.

Social comparison — and why Instagram amplifies it

Social comparison — measuring yourself against others — is a normal human behaviour, documented by psychologist Leon Festinger in 1954. What social media does is remove the limits that used to constrain it. You used to compare yourself to the thirty or so people in your immediate social world. Now it's billions of curated highlights. Nobody posts their bad days. You see your whole reality and their best moments, which is an inherently unfair comparison that your brain nonetheless takes seriously.

Ofcom's 2023 media literacy report found that 45% of 12 to 17 year olds said social media made them feel worse about how they look. That figure has been roughly consistent across surveys for the past seven years. Girls tend to report more negative effects from visual platforms (Instagram, TikTok); boys report more from gaming-adjacent platforms and competitive contexts.

Sleep — the most underrated effect

Screens emit blue-spectrum light that suppresses melatonin production — the hormone that signals to your body it's time to sleep. Using your phone in the 90 minutes before sleep pushes your sleep onset back, reduces total sleep, and reduces REM sleep quality. A sleep-deprived brain is more emotionally reactive, more prone to anxiety and depression, and less able to regulate mood. The phone-sleep-mood connection is one of the most well-evidenced links in the whole debate.

What the Online Safety Act now requires

Under the Online Safety Act 2023, platforms operating in the UK must now assess their impact on children's mental health, restrict harmful content for under-18s, and provide better controls. Ofcom is the regulator with enforcement powers. This is newer territory and enforcement is still developing, but the legal framework exists — and if you experience serious harm through a platform, you can report it to Ofcom.

Things you can actually do

• Audit your following list. If certain accounts consistently leave you feeling worse about yourself — even accounts you find aspirational — unfollow or mute them. You are not obligated to watch anyone's content.
• Turn off non-essential notifications. Most platforms allow you to keep DMs active while turning off likes, comments, and recommendations. Fewer interruptions means fewer compulsive check-ins.
• Set an app timer — but treat it as information first. Seeing how much time you actually spend is often more useful than the limit itself.
• Phone out of your bedroom at night. Not in your hand until you fall asleep. Charge it in another room. This single change has more evidence behind it than almost any other digital wellbeing intervention.
• Notice how you feel during and after. Not all use is the same. Scrolling alone at 1am feeling bad about yourself is different from messaging friends or watching something that makes you laugh.

The hardest part isn't what happens after you tell someone. It's the moment before — when you're about to say it and everything in you is looking for a reason not to. Young Minds research found that 70% of young people with mental health difficulties don't get help when those difficulties first appear. The gap between needing support and actually getting it is almost always about that moment before.

This article is about how to get through it.

The fear that stops people talking

The most common reason young people give for not telling anyone is some version of: "I don't want to be a burden." The second most common is: "I don't think they'll understand." The third is: "I don't know what to say."

All three are understandable. And all three, in most cases, are wrong. The people who care about you — whether that's a parent, a teacher, a friend, or a counsellor — would almost always rather know. Being told someone is struggling doesn't feel like a burden to most people. It feels like trust. The burden is carrying it alone.

You don't have to have the right words

One of the things that stops people is feeling like they need to have it figured out before they can talk about it. You don't. "I've been struggling lately and I wanted you to know" is a complete sentence. "I'm not doing as well as I probably seem" is a complete sentence. "I don't really know what's wrong, but something is" is a complete sentence.

You don't have to diagnose yourself. You don't have to have a list of symptoms or explain everything at once. The point of the first conversation is just to not be alone with it anymore. Everything else can come later.

Who to tell — and what happens next

A parent or trusted family member. If your home is safe, this is often the most useful first step because they can help you access further support. Most parents, when they find out their child is struggling, feel relieved to know — and want to help.

A teacher, form tutor, or school counsellor. Every secondary school in England has a designated safeguarding lead (DSL) and most have a counsellor. You can go to them directly, without telling your parents first. They are not allowed to tell other teachers casually — what you say is kept between you and the people who need to know to help you.

Your GP. You can book a GP appointment yourself from age 16 (and often younger — call and ask). Being honest with your GP about how you're feeling is not going to result in being locked away or sectioned — that's an extremely rare outcome reserved for people at immediate serious risk to themselves. What usually happens is: they listen, take you seriously, and discuss options. Those might include a referral to CAMHS, a local counselling service, or a check on whether anything physical might be contributing.

Childline (0800 1111). If none of those feel possible right now, this is a good starting point. Free, confidential, available every day and night. You can also use online chat at childline.org.uk. The counsellors there have heard everything — they won't panic, they won't judge, and they won't immediately tell anyone.

What if the first person you tell doesn't respond well?

This happens sometimes. A parent who dismisses it, a teacher who seems too busy, a friend who doesn't know what to say. It's disappointing, and it can feel like confirmation that you were right to keep quiet. It isn't. It means that particular person, in that particular moment, wasn't the right one.

You are allowed to try again. With a different person, or the same person on a different day. If a GP appointment feels unhelpful, you can ask to see a different GP, or ask specifically for a referral. You can contact Mind (mind.org.uk) or Young Minds (youngminds.org.uk) for guidance on pushing for appropriate support if you feel dismissed by services.
