My son and I have always been very close. We have identical personalities. He is very open with me (through choice) and never keeps anything to himself. He tells me everything. He has always been funny, entertaining, popular, lots of friends , everyone likes him .
Last year he had to have a circumsision, and a couple of months after he also had an accident , he had some injuries but they didn't scan his head. He was wearing a helmet . After this accident he became a completely different person at home, at school, with friends and with family. This was very noticeable. And very worrying.

He became aggressive, angry, pushed friends away, went after the "bad ones ", started vaping, got in ALOT of trouble at school and was aggressive and threatening to teachers . Completely out of character. We tried to speak to him about it alot but he would just get furious.
My parents who he is extremely close with sat him down and told him how worried they were. He was vile to them and told them he wouldnt see them again. We had to cancel holidays as he was horrible to be around and Xmas was very strained.
One day after Xmas, he woke up one morning and was back to normal, just like that. Went back to all his friends, doing great in school , loving and funny again and a joy to be around. We are all so happy about this , but it worries me why this happened?
I know kids have a horrible phase but this was intense and completely out of character.

I searched his room and went through his phone/pockets multiple times worried that hed been given drugs, or was being bullied/threatened. But there was absolutely nothing. We were worried he may have had a head injury from his accident. And of course it could have been a hormonal surge as hes in the thick of puberty but it was so severe.

Of course we will never know and he csnt explain it himself but has anyone else been through similar? Such a drastic change so quick to them go away as quick as it started?

Hello, didn't want to read and run.
Can I ask what the accident was? It sounds frightening and I would guess that he was scared and anxious by it, perhaps he suddenly realised that bad things can happen to him?
I feel like kids don't really realise until something life changing occurs- for me when I was 17 my young boss died with her 2 very young children and it was life changing for me- that moment you realise nothing stays the same forever.
I wonder if you son has had thoughts like this too.
Also, the hormonal surge is real too!
Hugs to you both

I think hormonal stuff can be pretty severe, although that sounds like a very short time - you do see quite a few posts here from parents bemoaning how an affectionate, open teen seems to have turned Mr-Hyde-style into an angry, sarcastic replacement so big changes do happen.

I know someone In a similar boat. It sounds as if your son has been recovering from the head injury/concussion. However that’s a long time to heal, especially for a young person. I’d be asking the GP for a referral for an MRI to eliminate issues that might be under the radar. (I know it’s a huge nuisance but better safe than sorry with head injuries.)

um an accident with a potential head injury sounds like the obvious reason,

pity they didn’t scan his head.
