Teen son suddenly self harming and fixated on girlfriend, any advice? ***TW: self harm and suicide ideation***

Sorry, a long one, but I am desperate and want to give as much info in the first post.

DS is 12 but almost 13 and deeply into physical puberty. I need advice, support, encouragement from others who have gone before because we are losing our minds with his sudden change of behaviour.

Three months ago DS was he usual happy delightful self. Struggled to focus at school but happy, jokey…really a brilliant kid. He had some bullying at school but was still his usually self. Then came a girlfriend and everything changed. She is full of angst - like a cloud moves over her head when she walks. Permanently online. Not very involved parents and we’re living in a country that doesn’t really believe in mental health.

We found messages from her that she was SHing and expressing suicide ideation. Within weeks, our happy go lucky son started to act/express the same thoughts. He doesn’t focus at all in class. Is defiant at home.

He has quite an obsessive personality but previously this has been channeled to normal kid interests - now it’s channeled at her. She was (the school tell me, we only joined recently) queen bee last year. After a failing out with all her friends she’s now a loner. Enter my DS. The school has described him as ‘collateral damage’ to her falling out with friends.

We still have large stretches of time where he’s more his old self - loving, funny, silly. he is still doing his extracurricular - football, track. But we can see from messages he sends that he’s talking about how he’s changed, no longer the same. The latest is telling her he doesn’t eat (he does, he had two dinners last night). This is all stuff she was telling him a few weeks ago. It’s like he learns behaviour and adopts it.

We have introduced restrictions on his computer to limit their messaging but now they use email and hard to stop that as he needs it for school.

We have limited resources for support where we are but have had a psychiatric evaluation and the conclusion is anxiety and non-suicidal self harm. He has cut himself and yesterday used an eraser to make the most dreadful red marks all over his arm. He will not engage in discussion about this. We try to remain calm, non judgmental, reassure him everything will be ok. He says we give him the hardest life - he has a really wonderful privileged life (with some notable challenge in that we have to move around for work but he’s always been very resilient and this hasn’t seemed to bother him much - and we don’t move too often - we try for 4 years per country. I know people might jump on this information (perhaps rightly) but just to say (1) this is his norm; (2) it’s norm for many of the kids he’s around; (3) our work is very hard to do from the UK). Moving school could be an option but it’s isn’t a good one - the other school here doesn’t have a good reputation). We’re a two parent loving, calm home. Financially we are not rich but stable and provide him with a lot (not spoiled but not wanting for anything).

We now finally have the first psychotherapy tonight (online - it’s the only option). I have shared a ton of information with the therapist who works with moving families like ours.

i don’t really know what I am asking but has anyone been through this and come out - with the SH particularly. But also with the total lack of focus at school. The school allow them to listen to music while working and this is such a distraction but when we blocked Spotify he lost it. We are trying to focus on stabilising his mental health and letting the school work slide for the moment.

Any words of wisdom? Do we show our concern or do we just keep calm? It’s so hard. I want the scream and throw things. But I don’t. I hate his behaviour right now, absolutely hate it. We both have super stressful jobs and while we don’t bring them home, this is impacting every element of our lives.

No one said it was normal. The previous poster said it was common in teenagers, which it is.

Do you always make things up to try and get your point across?

This has made my cry. Thank you. I feel really alone even though I have so many wonderful friends IRL. I want my boy back but I know that’s unrealistic.

In any event, changing my job is really really hard. It’s very specific and I am frankly incredibly fortunate to have it right now and keep not just a roof over our head but maintain a relatively nice (not luxurious) life.

He’s 12. The girlfriend will bugger off soon. You need to put this all in context. Obsessing over it will encourage Romeo and Juliet syndrome. They’re kids, treat them like kids. Take him to the cinema. Take him for walks. Make jokes. Show him happy is the right choice. He will be fine.

And take that bloody tech away.

Step off the career ladder for the next 5 -10 years and make your DC the priority. You settle somewhere longterm (UK?) and give him stability. Your DH can chase the work and return to you when on leave.

Basically this

ignore the psychiatrist saying don’t stop communication. He is 12 FGS

Trust me, as an ex ‘depressed self harming teen’ who seemed to be on the verge of suicide every 5 minutes (but looking back was just enjoying the high drama and thinking myself up my own bottom)

You’re doing the right thing in getting him some professional help. How confident are you of the school handling this competently? What makes the other school not an option? I feel it would be premature to quit your job and move.

The school is very communicative with us and they want to help. The school counsellor is experienced and I actually sit on the policy board so have a good relationship with them all. They are working with us on different approaches. They have banned the messaging app they were using to communicate.

BUT the mother of the girl is a teacher (this is all so outing but I don’t care!). It is also not a place where people typically seek mental health support. So it is highly unlikely the parents of the girl are seeking help. More than likely they have brushed it under the carpet.

I know the school will want to be seen to be acting - it is a very small community here and if I were to say negative things about the school it could have a big impact on them. Not that I am. I do think they are trying and are open to working with us. I get constant feedback.

We are letting the academic slide right now - is that the right choice? Focus on mental health? He’s bright but doesn’t apply himself. We could catch him up over summer with a tutor. Summer break starts here mid-June.

WhyTheHate · 22/05/2026 08:42

Oh, and what makes the other school not a good option - it has a bad reputation for student wellbeing and behaviour. I have friends with kids there. It would also mean moving from an American school to a British school and I fear he would really struggle academically as they are very different.

Summer holidays will be a great time to completely separate the two. You MUST end critical communication between them Op. it really is simple

It’s not so much a career ladder (although I have worked incredibly hard to get where I am!) as a way to support our family. My DH works in the same sector and he’s also lucky to have his job.

I also don’t know what that looks like in practice - he’s at school and extra curricular all day - I would just be sat at home. My employer is very flexible so I am with him A LOT. When he’s home at least one of his is home and at weekend it is all about him.

Your DC is 12, the academics dont matter at all in this situation. As PP remove all tech and get him outdoors and busy and away from the girl. Go off grid for the summer and build his resilience.
What wrong with the other school? Id look at moving over the holidays for a fresh start.

I am hearing the message from everyone about the comms with the girlfriend. It is hard to end completely but we can severely restrict. He doesn’t have a smartphone. Tech is basically off by 9pm. We have a no tech in the bedroom rule.

He says he ‘overthinks’ and I see this causes him to spiral (worrying about her). So when we do limit apps or screen time he loses it. We can and have done it anyway. We just didn’t want him losing it to the extent he becomes even more of a danger to himself.

He has a first CBT session tonight and two more next week. I will seek advice on this from the (new) psychotherapist.

As an ex international schoolgoer, the American schools always had a worse reputation for education and behaviour than the British schools. Have you talked to the other school at least? Are local schools out of the question? Explore all your options.

Mummyoflittledragon · 22/05/2026 08:51

Move him to the British school. Unless things have changed, my understanding is the level of education by age is higher.

WhyTheHate · 22/05/2026 08:52

It feel a bit like he is trying on a new personality for size - I don’t know if anyone can understand what I mean? He loves music and is listening to Radiohead, Smashing Pumpkins, Pixies, etc…he has started to dress very ‘indie’ (all fine - I did all of this!). But it feels a bit like he’s decided this is his new personality and almost…performative? I am not minimising the self harm (see above!) but trying to understand where it has come from.

Thank you everyone for your responses so far.

All he’s going to do is ruminate on the girlfriend with them. It’s pointless. Sorry but I’m of the camp that therapy is quite damaging and encourages harmful introspection unless desperately needed.

Proseccoismyfriend · 22/05/2026 08:54

If he feels like wanting to harm himself suggest holding ice cubes

Yes local school totally not an option (unless he learns an incredibly complicated language very quickly). Plus they have a TERRIBLE reputation for bullying.

The other complicating factor with the British school is that he previously went to British school but in the year below. When we moved here this British school refused to allow him to enter at the year he’d studied up to - saying it is an immovable policy for kids to study at their year of birth. Essentially he’d skip a year of learning. I am not dismissing the idea - we are exploring it and keeping all options on the table - just explaining why it’s not so straight forward.

Yes because it’s a performance. It isn’t real. He’s hamming it up to appear interesting and deep to the new girlfriend. You’re now telling him it’s all real by panicking and shipping him off to therapy.

WhyTheHate · 22/05/2026 08:58

The British school is not even the school of choice for British embassy staff. I have lived all over the place and this is quite unusual. They have just excluded one boy and are about to exclude two girls. Also unusual for these private international schools so the behaviour was quite extreme.

From what op has said about the girlfriend, it wouldn’t surprise me if she is enjoying the drama. And so perhaps the right approach for her is to ignore it. Idk.

However, the nuance here is that we aren’t talking about the girlfriend, we are talking about op’s ds. And we don’t know what it’s like for op’s ds.

Telling op the problem will just go away isn’t useful. I thought that about my dd and her Eating Disorder. Just a phase. Yet she became so mentally ill that she believed she didn’t need to eat to live. And I literally saved her life.

Op needs to take a cautious approach. But not presume he is going to go the same way as either you or my dd.

Agree- do you and dh have leave over summer? Can you do regular fun stuff with him? Even maybe if he has a "fun" uncle or aunt or involved gps could they come for a holiday and do lots of stuff with him? Whatever, outside, off tech, away from her.
And dont quit your job, you could end up jobless, back here, without a house and then having to negotiate the school system which often isnt great for pastoral care.
Good luck op.

Eating disorders are completely different.

20 years ago teenagers going through a ‘depressed, deep, alternative’ phase was so normal it was almost expected. It’s only now it’s being treated as a mental health issue that needs therapy and medication. Out of the dozens of kids I knew like this growing up, all have grown out of it and now have sensible boring lives.

Out of all the teens on here in more recent years who have been mithered by their parents and shipped off to therapy and for diagnoses, none seem to ever make a meaningful recovery. Their life becomes being pandered to, overthinking everything, blaming their diagnosis and growing into the person ‘who is mentally unwell and can’t be expected to do anything’.

We urgently need to go back to ignoring these phases, while still providing a happy and safe home, rather than entrenching the identity crisis by treating it as a mental health issue. Look at ‘trans’ and where we ended up with that.
