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.

Tell school everything

Stop any and all interaction between these two outside of school. Both in person and virtually.

He is very young. So don’t be afraid to parent him.

If this continues, change schools to get him away from her.

please reassure me that you went straight to the school?

XelaM · 22/05/2026 06:23

Change schools to get him away from her asap

Mummyoflittledragon · 22/05/2026 06:55

Personally and having lived the lifestyle you’re discussing for a decade, if you can’t sort this out asap, I would return to the uk or whatever your country of origin is. My voice includes experience of a child, who is severely mentally unwell. And my 17 yo dd was born and lived in one place her whole life as we returned to the uk just before her birth. Rent a house and choose your location wisely based on catchment for a really good, not too large secondary school.

Teens ‘self harming’ and threatening suicide is very common.

Stay calm. Ban the girlfriend. Keep him busy outside of school. Take the devices away and WiFi off by 9pm. Watch him flourish.

😱 not the teens I know. Self-harming is horrific and very serious behaviour, not within the realms of normal at all

No, we all did it at school (emo days). Teens are very dramatic, thankfully it’s very rare for one to actually end their lives. It’s a good way of guilting parents though.

Ok so you and your friends did it.

I didn’t. My friends didn’t. My sister didn’t, her friends didn’t, my brother didn’t, his friends didn’t.

You wouldn’t know if they had. They probably wouldn’t tell you. It’s definitely been on the uptick since the 2000s, it started with emo then became an online fad. Thankfully teen suicides peaked in the 80s, and have been lower since.

But you said you and your friends did it. They told you.

So works the other way too if they don’t do it.

This was the 80s/90s

i now have teens (do you?) and neither do and neither have ever mentioned friends that do (and we talk pretty freely)

Alateone · 22/05/2026 08:26

nope, not all

WhyTheHate · 22/05/2026 08:27

Yes, I went to school and shared the evidence. They have spoken to the parents.

The advice from the psychiatrist is not to ban access (this is hard anyway as they are in class together). He doesn’t see her outside school though.

Moving school is not easy - there is one other school here and it is not good.

I will start to look for work elsewhere but this is also not easy - my sector has been really badly hit and as I have worked overseas for many many years, getting a job in the UK is not easy. Friends who lost their jobs last year are still out of work. Financially, we need my income (my husband works remotely). But I am exploring these options.

Unfortunately the data I have seen shows that non-suicidal self injury among young people is not uncommon. Whether that’s self inflicted injury, eating disorders, substance abuse. Believe me, we are treating this as very Not Normal and we are petrified but I also know we aren’t the only ones in this situation. I guess I want reassurance that with the right intervention we can get through this.

We are trying to keep him busy outside school - lots of activities. We will be stricter with the computer (he doesn’t have a smartphone - thank god).

Then you’ve probably had a very nice upbringing and lived a very sheltered life. I doubt your brothers friends would tell you, I meant. The other poster agrees with me.

Op you don’t need to be petrified. It’s stunningly unlikely he will seriously harm himself in any way. Hes trying to impress the girlfriend. Changing your job is a massive overreaction. Keep him living in the real world and off the tech. Keep things light and happy. Don’t justify and enable his neuroses by obsessing over it.

WhyTheHate · 22/05/2026 08:31

Just on the discussion about whether this is normal - of course it gives me comfort to know (think?) this isn’t unusual. The data does seem to back that up (I read something yesterday that says 17% of young people studied report non-suicidal self injury and that’s not counting other forms of self harm). But it isn’t healthy and is it dangerous. A close relative of mine engaged in very serious SH as a child and I had a friend at university who was the same (she’s a vicar now!).

So to be clear… you really do think all were doing this?

Stop that. He is 12!! Stop virtual communication now.

Just stop. Your desperation to pick on every word out of context just makes you look mad.

Bikenutz · 22/05/2026 08:34

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.

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.

Agree. Take back control. Stop playing the game. My parents ignored my ‘depression and self harm’, they kept me busy and things happy and fun at home. I got past it.
