Why Is My Teenager So Hard on Themselves?

By Vanessa Bailey, MBACP 

 

You’re standing in the kitchen getting ready to leave when your teenager walks in, looks at themselves in the mirror and immediately pulls a face. “I look disgusting.” You automatically reply, “You don’t! You look lovely.” They disagree, you reassure them again, they disagree even more strongly and somehow what started as you trying to make them feel better has turned into a debate you have absolutely no chance of winning.

Maybe it isn’t appearance. They get a good mark at school and immediately tell you about the three people who got higher. Someone compliments their drawing and they point out everything that’s wrong with it. They make one mistake and suddenly they’re “so stupid.” A friend doesn’t reply for a few hours and their brain decides it’s because nobody actually likes them.

As a parent, it can be really difficult to listen to because you’re looking at this person you love and seeing all of the things they apparently can’t see in themselves. So naturally, you try to convince them. You tell them they’re clever, beautiful, funny, talented, kind and absolutely good enough. The frustrating part is that sometimes the more reassurance you give them, the less they seem to believe you.

So what’s actually going on?

Why doesn’t reassurance work?

Imagine somebody repeatedly telling you something about yourself that you completely don’t believe. If someone kept telling you that you were seven feet tall, you’d probably think, Why do they keep saying this? I know I’m not. That’s sometimes what reassurance can feel like when a young person’s view of themselves has become really negative.

You say, “You’re beautiful,” but inside they’re thinking, You have to say that. You’re my mum. You tell them they’re clever and they remember the question they couldn’t answer in class. You tell them people like them and their mind immediately goes to the friend who left them out last weekend.

The problem isn’t necessarily that they haven’t heard enough positive things about themselves. It’s that those positive things don’t match the story they currently believe. And once our brain has decided something is true, it can become remarkably good at collecting evidence to prove itself right while conveniently ignoring everything that doesn’t fit.

This is why simply piling on more compliments doesn’t always change things. Your teenager may genuinely know that you think they’re wonderful. What they’re struggling with is believing it for themselves.

Growing up surrounded by comparison

Being a teenager has probably always involved comparing yourself with other people, but teenagers today aren’t only comparing themselves with the people sitting next to them in class. They’re comparing themselves with hundreds of people every time they pick up their phone.

Someone is prettier, someone has clearer skin, someone has more friends, someone is thinner, someone has better clothes, someone got higher grades, someone is already in a relationship. Someone’s Saturday night apparently involved a beautiful group of friends watching the sunset while your teenager spent theirs eating cereal and scrolling through TikTok.

What they don’t see is the forty photographs that weren’t posted, the argument that happened ten minutes earlier, the insecurity behind the picture or the fact that the person they’re comparing themselves with might be lying in bed later doing exactly the same thing.

Social media gives teenagers access to everybody else’s highlight reel while they experience their own life completely unedited. That’s a pretty unfair comparison, particularly when you’re still trying to work out who you are and where you fit in.

“I’m so stupid”

Sometimes the horrible things teenagers say about themselves aren’t really about the thing they’re talking about. “I’m stupid” might actually mean I’m embarrassed. “I’m ugly” might mean I’m scared people are judging me. “Nobody likes me” might mean I feel left out. And “I can’t do anything right” might really mean I made a mistake and I don’t know how to cope with how that feels.

Teenagers don’t always have the language to explain the more complicated feeling underneath. Sometimes they don’t even fully understand it themselves. They just know that something feels horrible and their brain quickly turns that feeling into a judgement about who they are.

Sometimes saying something horrible about themselves first can even feel protective. If I tell myself I’m rubbish before anybody else gets the chance to, maybe it won’t hurt quite as much if somebody else thinks it too. If I already expect rejection, perhaps I can convince myself I wasn’t bothered when it happens.

It can sound dramatic from the outside, but underneath there is often a young person trying to protect themselves from feeling embarrassed, rejected or not good enough.

Perfectionism doesn’t always look like trying really hard

When we think about perfectionism, we often picture the teenager staying up until midnight making sure their homework is absolutely flawless. And yes, it can look like that. But perfectionism can also look surprisingly like not trying at all.

If I don’t try, I can’t fail. If I don’t submit the work, nobody can tell me it wasn’t good enough. If I don’t audition, I can’t be rejected. If I pretend I don’t care about the test, getting a bad mark won’t feel quite as embarrassing.

Sometimes the teenager who appears completely unmotivated actually cares far too much. The possibility of getting something wrong feels so uncomfortable that avoiding it altogether feels safer. This is particularly important when adults keep saying things like, “You’re so clever, you could do it if you just tried.” They may already know that, and that might actually be part of the pressure.

Underneath what looks like laziness or lack of motivation can sometimes be a teenager quietly thinking, What if I actually try my hardest and discover I’m still not good enough?

When your teenager is neurodivergent

For teenagers with ADHD or autism, years of feeling slightly different can have a huge impact on how they see themselves. They may have spent years hearing versions of “stop interrupting,” “why haven’t you done this yet?”, “you need to concentrate,” “everyone else has managed it,” “you’re too sensitive” or “why can’t you just do it?”

Most of those comments probably weren’t intended to damage their confidence. They’re often said by adults who are frustrated, confused or genuinely trying to help. But when a young person hears versions of the same message repeatedly, it can slowly become part of the way they talk to themselves.

Eventually nobody else needs to say, “Why can’t you just do it?” because they’re already saying it internally.

They may also be working incredibly hard to do things that seem to come naturally to other teenagers. Keeping track of homework, navigating friendships, coping with noisy classrooms, remembering instructions, managing rejection, understanding social situations and simply getting through a full school day can take an enormous amount of energy.

The problem is that they don’t necessarily see the effort they’re putting in. They look around and think everybody else is coping effortlessly while they’re struggling with things that are apparently “easy.” Over time, it’s very easy for this is harder for me to turn into there must be something wrong with me.

Those are two very different things.

Why do they reject every compliment?

This can drive parents slightly mad. You say something nice, they disagree. You explain why you mean it, they disagree again. You provide evidence and somehow they produce counter-evidence. Before you know it, you’ve accidentally entered a courtroom where you’re defending the case of My Child Is Actually Lovely and they’re acting as the prosecution.

You don’t always have to win that argument.

Sometimes rather than immediately trying to convince them that what they’re saying isn’t true, it can help to become curious about why it feels true to them. If they say, “I look disgusting,” instead of immediately responding with, “Don’t be silly, you’re gorgeous,” you might say, “You seem really unhappy with how you look today.” If they say, “Nobody likes me,” you could try, “It sounds like you’re feeling really left out at the moment.”

You’re not agreeing that they’re ugly, stupid or unlikeable. You’re responding to the feeling underneath what they’re saying. And often, that’s the bit that actually needs you.

They’re watching how you speak to yourself too

Teenagers learn a surprising amount about how to relate to themselves by watching the adults around them. That doesn’t mean parents need to model perfect self-esteem. Nobody needs that pressure, and teenagers can spot fake positivity from approximately three miles away anyway.

But it can be worth noticing the everyday things they hear. If your teenager regularly hears you looking in the mirror and saying you look horrible, refusing photographs because you hate your body, calling yourself stupid when you make a mistake or constantly criticising yourself, they may begin applying some of those same rules to themselves.

Modelling self-compassion doesn’t have to mean standing in front of the mirror announcing how beautiful you are. It can be much more ordinary. “I made a mistake, I’ll sort it.” “I don’t particularly like this photo of myself, but I’m keeping it because we had such a lovely day.” “I’ve had a difficult week and I think I need some rest.”

You’re showing them that you can be imperfect without turning against yourself.

How therapy can help

Parents sometimes worry that suggesting therapy will accidentally confirm their teenager’s fear that something is wrong with them. It doesn’t have to. Therapy isn’t about taking a teenager who struggles with confidence and spending fifty minutes trying to convince them they’re amazing. To be fair, most teenagers would find that incredibly annoying anyway.

Instead, we get curious about what’s happening underneath. Where did this critical voice come from? When did they start believing they weren’t good enough? What happens internally when they make a mistake? What does rejection mean to them? Whose standards are they actually trying to reach?

For some young people there might have been bullying, difficult friendships, family experiences or other painful things that have shaped how they see themselves. For others, years of feeling different, misunderstood or unable to meet expectations have slowly chipped away at their confidence. And sometimes there isn’t one big explanation at all. Their relationship with themselves has been shaped by hundreds of small experiences over time.

Therapy gives us somewhere to start untangling those experiences without making the teenager feel like they’re the problem that needs fixing. And therapy with teenagers doesn’t always mean sitting opposite each other having an incredibly serious conversation for fifty minutes. We might talk while playing Uno, doodling, making something or simply doing something with our hands. Sometimes the important conversation appears while we’re apparently talking about something completely unrelated.

The relationship comes first. I’m not particularly interested in teaching a teenager how to perform confidence or giving them a list of positive affirmations to repeat when they don’t believe a word of them. I’m much more interested in helping them understand themselves, recognise where that harsh internal voice comes from and gradually develop a kinder, more realistic relationship with themselves.

They don’t have to love everything about themselves

There’s a lot of pressure around self-love now. Love your body, love your flaws, love yourself. It’s a lovely idea, but sometimes it’s an enormous leap for a teenager who currently doesn’t particularly like themselves.

Maybe we don’t need to start there.

Maybe the first step is simply helping them become a little less cruel to themselves. To make a mistake without deciding they’re stupid, have a friendship fall apart without deciding they’re unlikeable, dislike a photograph without deciding they’re ugly, or struggle with something without deciding they’re a failure.

Your teenager doesn’t need to believe they’re the cleverest, funniest, most attractive or most talented person in the room. They don’t need endless confidence and they definitely don’t need to love every single thing about themselves.

They just need to slowly learn that their worth isn’t dependent on being any of those things.

So when they say, “I’m rubbish at everything,” your job isn’t always to immediately prove them wrong. Sometimes it’s being curious about what’s happened to make them feel that way, listening without immediately trying to fix it and staying beside them while they work it out.

Because beneath the eye rolls, slammed doors, “I don’t knows” and arguments with every compliment you give them, there may simply be a young person trying to work out who they are.

And hopefully, with the right support, they can learn that struggling, getting things wrong and being different don’t make them any less worthy of liking the person they’re becoming.
