I’ve been through this and believe me I am not and have never been a permissive parent.
My DS was 11 when he went to secondary school. I’d never had a moment of trouble from him until that moment.
Within two weeks of starting he was involved in a fight. When I received the call I honestly thought they had mixed him up with someone else.
What followed was four years of hell on earth. I won’t bore you with the details but he was self harming (cutting), fighting, smoking, drinking, smoking weed, damaging property, swearing, having sex, stealing. You name it and he did it.
I tried everything. Grounding, taking away his stuff, removing his access to tech, shouting, talking to him - nothing worked.
He had numerous doctors appointments, referrals to CAMHS and I was told he was just badly behaved.
I finally managed to get him on a waiting list to see a clinical psychologist as someone who saw him at an emergency CAMHS meeting thought he showed traits of ASD.
Anyway he was permanently excluded from school in June 2019, and was deemed too volatile to be placed in a PRU. He got a key worker and some tuition at home in maths and English and was sent on vocational courses in small groups.
In December 2019 at 15 years old he was diagnosed with ASD by the two clinical psychologists who saw him. They basically said that he masked at primary school and could do this because the routine was strict and regimented. He simply could not cope with secondary school and reacted really, really badly. He was self medicating with drugs and alcohol and cutting himself because it made him calmer.
He’s 16 now and at college. My god he’s not perfect but he’s almost back to being my son again. He doesn’t go out much now and prefers to stay at home. He still smokes and has the odd beer but , to be honest I thought he’d be in prison by now so I don’t care about the odd bottle of Budweiser. He still gets angry but is more able to manage his emotions.
Don’t assume there is nothing lurking behind this behaviour. All behaviour has a reason.
There is no magic bullet here. I moved my son to a different school. He simply took his behaviour with him. Trust me when I say I was on the edge of a complete mental collapse at times.
I’m sorry I can’t give you any ideas about hobbies etc but sometimes these things just do not work. My son did kickboxing for a while. He was very good at it and it made him even better at fighting. So that was a waste of time. And if I’d suggested cadets or whatever he just wouldn’t have gone. As he was over 6ft tall at 12 I couldn’t have made him go either.
My advice is keep,talking. Don’t lose your temper. Try and talk to him in the car (less confrontational). Keep calm if you can. Shouting at my child simply does not work, so I don’t do it.
My DS repeats back to me things I said to him when he was in trouble all the time. He was listening but he couldn’t do anything with the advice then because he wasn’t in the right place. But, if your son is still in there somewhere, he will be listening at some level to what you are saying.
I know how this feels and it’s terrifying but keep talking to him.You are his mum and he needs you, whether he thinks he’s the big man or not.
