Why bother?
You already know a lot about yourself. You know which songs you want on repeat, which jumper you'd wear every day if you were allowed, and which room in the house you go to when everything has got too loud.
What you might not have done is put all of that into words.
That matters more than it sounds. When you can say "bright overhead lights give me a headache" instead of just feeling awful in maths and not knowing why, you can ask for something different. When you know that you need forty minutes alone after school before you can talk to anyone, you can protect that time instead of feeling guilty about it.
Nobody else can do this bit for you. Teachers, parents and doctors can notice things from the outside, but you're the only one inside your head. This guide is here to give you some words and some questions. The answers are yours.
Starting with your brain
Brains are not all built the same way. They take in information differently, sort it differently, and react to it differently. The word for that variation across the whole population is neurodiversity — the simple fact that human brains vary.
A few words you'll come across:
Neurodivergent — a person whose brain works differently from what's typical where they live. Autistic people often use this word. So do people with ADHD, dyslexia, dyspraxia, Tourette's and others.
Neurotypical — a person whose brain works in the way most people around them expect. Not better. Just more common, which means the world tends to be built for them by accident.
Autistic — a person who processes information, communicates and experiences the world in a way that differs from non-autistic people. It isn't an illness and it isn't something that gets fixed. It's how your brain is wired, and it will be how your brain is wired when you're eighty.
You'll notice this guide says autistic person rather than person with autism. Most autistic adults prefer it that way, because autism isn't a bag you're carrying — it's part of how you think. But some people prefer it the other way round, and that's their call. Use whichever fits you.
One more thing before we go on. Being unusual isn't the same as being worse. Every genuinely new idea in history came from someone whose brain went somewhere other people's hadn't. A world where everyone processed things identically would be a world that stopped moving.
Your senses
Most people can name five senses. There are eight.
The familiar ones: sight, hearing, touch, taste and smell.
Then three that don't get taught as often:
Balance and movement (vestibular). Where you are in space when you're moving — spinning, swinging, tipping backwards, going down stairs. Some people can't get enough of this and will spin until they fall over. Others feel sick on a gentle roundabout.
Body awareness (proprioception). Knowing where your arms and legs are without looking. It's what tells you how hard to squeeze a paper cup, or that your foot is about to hit the step. If this sense is quiet, you might bump into doorframes, press too hard with a pencil, or crave big squeezing hugs and heavy blankets.
Internal feedback (interoception). Your body reporting on itself. Hungry, thirsty, too hot, need the loo, heart racing, going to be sick. Lots of autistic people get a weak or delayed signal here — you don't notice you're hungry until you're suddenly furious, or you don't realise you're ill until you're properly ill.
There's no single autistic sensory profile
People assume autistic means sensitive to everything. It doesn't. You can be flattened by the sound of a hand dryer and completely unbothered by a cut on your hand you didn't notice happening. Most people are a mix: some senses turned up too loud, some turned down too quiet, and it shifts depending on how tired or stressed you are.
Some of the ways this shows up:
- Sounds other people don't seem to hear at all — strip lights buzzing, a clock, someone's breathing
- Food that's impossible because of texture rather than taste
- Clothing labels, seams, waistbands, socks
- Not registering cold, or pain, or a full bladder until it's urgent
- Craving strong flavours, strong smells, deep pressure, or constant movement
- Everything blurring into noise when you're already stressed
What helps
The point of noticing all this isn't to make a list of problems. It's so you can do something about it.
Turning something down: ear defenders or loop earplugs, sunglasses indoors, a hood up, sitting at the edge of a room rather than the middle, eating somewhere other than the dining hall, choosing clothes by feel and buying five of the good one.
Turning something up when you need more input: chewing gum, a heavy bag on your lap, cold water, a walk, something to fiddle with, loud music through headphones.
Neither is cheating. They're tools, the same as glasses.
Stimming
Stimming is repetitive movement or sound that regulates you: rocking, hand flapping, pacing, bouncing a leg, twirling hair, clicking a pen, humming, lining things up, replaying the same eleven seconds of a song for an hour.
It does a job. It burns off excess input, or supplies input you're short of, or gives your body something predictable to hold onto while everything else is unpredictable. People stim when they're anxious, and also when they're delighted.
You may have been told to stop. Sitting on your hands doesn't remove the need — it just moves it somewhere less visible and more tiring. Unless a stim is actually hurting you, in which case it's worth asking someone for help finding a substitute, there is nothing wrong with it.
The things you love
Autistic interests tend to run deep. Not "I quite like trains" but knowing the rolling stock, the routes, the signalling system and the year each depot opened.
The subject can be anything: a video game, weather systems, a band, hedgehogs, the London Underground, a particular film watched eighty times, sharks, a person, spreadsheets. It might last a fortnight or the rest of your life.
These aren't a distraction from real life. They tend to be the thing that:
- Reliably makes you feel good, including on days when nothing else does
- Gets you talking to people who care about the same thing
- Gives you somewhere to put your attention when your mood is bad
- Turns into a skill, and sometimes a job
People occasionally treat an intense interest as a problem to be limited. Unless it's illegal or hurting someone, it isn't. It's one of the more reliable sources of good feeling you've got. Guard it.
How you communicate
Autistic communication isn't broken communication. It's a different style — and when two autistic people talk to each other, it usually works fine. The friction shows up between styles, and it goes both ways.
Words vary. Some autistic people talk constantly. Some use a handful of words. Some don't speak at all and communicate by typing, signing, gesture or AAC device. Some talk easily at home and go silent at school. All of these are communication. None is a lesser version of the others.
Literal versus indirect. You may say what you mean and expect the same back. Much of the time you won't get it:
- "I don't mind, whatever you want" often means they do mind and want you to guess
- "We should catch up sometime" is frequently just a polite way to end a conversation
- "Everyone's going" means "I'd like you to come," not that everyone is going
- Sarcasm means the opposite of the words, signalled by a tone you may or may not catch
You're not failing to understand. You're translating, and translation takes time. Asking "do you mean that literally?" is a completely reasonable question, even if people find it startling.
Honesty. You'll be told to be honest and then told off for it. If someone shows you a new haircut and you say you don't like it, you were being helpful and accurate. They heard an attack. The unwritten rule is that "do you like it?" often isn't a real question — it's a request for reassurance. Knowing this doesn't mean you have to lie. "It's very different!" and "the colour really suits you" are both true and both survive the moment.
Faces and eyes. Body language, expression and eye contact carry a lot of meaning for non-autistic people. Reading them can be hard work, and holding eye contact can be genuinely uncomfortable — some autistic people describe it as painful, or say they can either look at someone or listen to them, but not both. Looking at someone's forehead, or at the table, doesn't mean you aren't listening.
Masking
Masking is hiding your autistic self to fit in.
It looks like: copying other people's expressions, forcing eye contact, rehearsing conversations before you have them, laughing at things you don't find funny, pretending to like what the group likes, holding in a stim until you're alone, borrowing someone's accent or turn of phrase, dressing to blend rather than to please yourself.
Some people mask deliberately. Some have done it so long they can't feel themselves doing it, and only realise years later that they don't know what they actually like.
Two things are true at once, and both matter.
Masking is not shameful. It's often a sensible response to an environment that punishes difference. Sometimes it's a safety strategy, and you get to decide when you need it.
Masking is also expensive. It runs on effort you can't see the meter for, and the bill arrives afterwards — the meltdown at home after a fine day at school, the total flatness at the weekend, the exhaustion that sleep doesn't touch. Long-term, heavy masking is linked to burnout and to feeling like you've lost track of who you are.
So the aim isn't to stop masking. It's to have places where you don't have to. One room, one person, one afternoon a week where you stim freely, talk about your thing at full length, wear the comfortable thing and don't perform. That's where you find out what you're actually like.
Recovery is personal. It might be silence, or a screen, or your interest, or being near someone safe who doesn't need you to talk. Work out what yours is, and treat it as necessary rather than lazy.
Things that change
Familiarity is steadying. Routine means fewer unknowns to process, which leaves more capacity for everything else. Which is exactly why the teenage years are hard: nearly everything changes at once, and most of it without warning.
Your body. Puberty changes your height, voice, skin, hair, smell and shape, and none of it asks permission. If your interoception is unreliable, this is worse — new sensations arrive that you can't name or predict.
Your friends. People you've known for years start behaving differently. Groups reshuffle. Things you all did last year are suddenly "for kids". Some people get colder, or start being unkind for reasons that make no sense.
The rules get invisible. Younger children's rules are stated out loud. Teenage rules mostly aren't. There are expectations about clothes, music, what you can admit to liking and how much you're allowed to care about it — and nobody publishes them.
Here's something worth knowing: a lot of your peers don't understand these rules either. They're guessing, and copying, and pretending to like things so they don't get left out. When someone claims not to like something you know they love, that's usually what's happening. It can look like everyone else got the manual. Mostly they didn't.
More decisions. Peer pressure, choices about your appearance, food, money, time, plus adults expecting you to be more independent than you were last year.
School gets heavier. Exams, options, and constant questions about what you're doing afterwards — often before you have any way of knowing.
That's a lot of change landing on a brain that runs best on predictability. If you're finding this stretch of life harder than the people around you seem to, that isn't weakness. There's genuinely more to process.
Build your own guide
Everything above is general. This part is yours. Write it down somewhere — phone notes, paper, wherever you'll find it again — and add to it as you notice things.
Sensory
- Three things that reliably feel good
- Three things I can't cope with
- Sounds, lights, textures, smells, foods to avoid
- What I do to calm down; what I do when I need more input
- My stims

- How I prefer to be asked things
- Whether I need time before answering
- What helps when I've stopped being able to talk
- What people misread about me
Energy
- What drains me fastest
- What actually refills me
- Early signs I'm running low, before it becomes a meltdown or shutdown
- How much recovery I need after a hard day
Me

- Places I don't have to mask
- People I don't have to mask around
- What I'm good at
- What I want more of
There's no finished version. You'll change, and the list changes with you. But even a rough one gives you something to hand to a teacher, a new support worker or a friend who wants to get it right — and it means the next time someone asks what you need, you won't have to invent an answer on the spot.
Where to go next
Understanding yourself is one half. The other half is finding people who'll listen once you do — a teacher who adjusts the lighting, a friend who lets you talk about your subject for twenty minutes, a parent who stops asking why you're tired after a normal day.
Start with one person. Show them one thing from your list.
