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.

🙄

I seriously despair at people normalising self harm 😱 No, it is not normal! No, most teenagers don't do it and never did in my day. It's horrifying that this is normalised as some cool teen experience. It absolutely is not!!!! 🤦‍♀️ I have a teen daughter and was a teenager myself many years ago and have a younger brother. Absolutely no one I know or my teen knows has ever engaged in this

Keepgettingolder81 · 22/05/2026 16:24

Do you know the parents? Go and see them to keep their daughter well away from your family.

I do - the mother is a teacher at the school. A complicating factor. I have been advised not to have any direct contact (anyway her father doesn’t speak English) so doing it all through the school.

Ok so…..

every single day you check all messages that he has sent whilst at school

at home he has no SM and he can’t message this girl on any app.

at the end of the day, he hands over his phone and you check every platform / app he has access to

She and he never get together outside of school

So… how are all these messages getting through?

Anonanonanonagain · 22/05/2026 17:00

Go into his computer and block her messages then every day before he opens it go to the junk folder and clear it out.

Sweepyed · 22/05/2026 17:00

My kid is 14yo.
They are severely depressed and SH suicidal etc. CAMHs is absolutely useless and rejected.
i do think its a problem that there is contagion probably usually online.

out of my friend group 1/4 did SH i know of.

It sounds like ops son isnt actually depressed just realised it can be a way to get what you want.
However when mine was telling others online they were severely depressed they were actually happily (?) playing a computer game.
When they started secondary the trans stuff was rife with school clubs etc and that has i think largely led this was to not being happy as they are

Hassell · 22/05/2026 17:04

Every single day you need to be on top of this. In fact t ALL over this. You check every outlet that he can possibly message every single day.

Right now it is mainly his school email address while he’s at school. Everything else is locked down apart from the PS which he doesn’t use much/she doesn’t have one. We have now blocked access to Outlook at home, as of tonight. I will ask the school how important it is that he accesses during school (mainly teachers use Teams and the kids aren’t able to DM on Teams).

He has a brick phone which he uses to listen to music and we allow 5 mins of access to for SMSing. Sometimes he asks and usually he doesn’t. We consulted a paediatric psychiatrist who advised to limit but not totally block contact.

I understand the focus on the tech but they also have physical access to each other at school. I have asked that they are moved away from each other in class and this has happened. But they are together at recess.

Today I found out that he learned the eraser technique for SH from her (not over messages - in person). I am at the school
tomorrow for an event so will inform the Director.

To the poster saying this is abnormal - I know. That’s why I am trying to deal with it. It’s an unhealthy coping mechanism. But regardless of whether you or your teens or their friends did it - it does happen. Since confiding in friends, I have had numerous tell me they had similar with their kids or kids in their family.

You’re right - his psychiatric evaluations have come back as scoring very low for depression but high for anxiety. He has experienced bullying (he has a distinguishing feature which makes him a target) so I think it’s connected to this as well as potentially other triggers.

Cut all contact with the girl. Don’t listen to the psychiatrist it needs to be stopped for his sake.
there does seem to be more teens engaging in this sort of behaviour. I’ve raised two and it’s not easy to navigate but keep him busy, off tech and away from her as much as you can would be a good start

So atm ONLY outlook messaging at school.

Every day you check.
Every message that is inappropriate - you forward to school and tell him no XYZ. He is 12. Must be something you can withdraw or restrict.

Would you pull him out of school early for summer? Just separate them asap and hope for better after the break? But if you are going to be in the same school long term, with such a small year group , you really have to look for another school.

Yes - I actually discussed this with the school and have permission for him to leave early. If things don’t stabilise quickly we will pull him out and his father will take him back to the UK to start his summer early and be with grandparents _

I am living in a very small place so I know all other schools - there is one and it’s not a good option for the reasons I mentioned. Not to say we aren’t considering it but there is a real risk it could be a very bad decision so need to think it through carefully (which we are).

Take back control.. More sport. More family holidays. Turn off wifi after school.
Ban girlfriend.
Tell school that girl is to have minimal contact.
Invite other team mates and their families (mixed sex) over for BbQs. Take DS on joint bush walks with other healthy families.
Ship DS off to grandparents for small holidays if you can not look after him properly during school holidays.

Nip in the bud with reality of a flood of good people and hobbies around DS.
Spend on camping trip with his Dad rather than counselling.
Search and find and engage with the old DS.

The child is 12. The OP and father need to get firm. Really firm

I can imagine it’s a hard decision. Can you plug the gaps over the holidays a little? Maybe get your ds in summer school in the U.K. for at least the number of weeks he’ll be missing at his current school for example. That way you have options.

As for changing school, would you not be able to trial for a term the British school and if it doesn’t work out, go back to the American? As its fee paying, I would have thought they’re unlikely to refuse to take your ds back.

We are lucky to have active grandparents and we also have a lovely holiday planned. Plus it’s a 9 week holiday here.

The term trial is an idea and I will speak to them about it, thank you.
