OK, firstly, is it him who called the police?
What was the issue that led to him hitting you and you retaliating?
Has the situation of conflict come about recently or have you always had issues with him?
Are you able to talk to him when he comes down and understand what brings on the anger?
Anger is a common feeling that comes on during teenagehood. It hit my boy at 12 and certainly shook me too. When he is angry, he is very angry and it is hard not to take his attacks (never physical in his case) personally. However, I've learned that he is as upset with it as I am. One day, I came home and he was crying and shaking on the floor because he'd broken something in anger and he was totally distressed saying 'why do I get so angry, why can't I control myself'.
After that episode, we talked a lot. Firstly about how anger is not all bad because a small level of anger can be what gives you energy to make changes in your life that you need to make, but that when it becomes uncontrollable, that's when it becomes destructible. We then discussed how he could learn to recognise the signs when it is coming and what he can do to avoid it exploding.
I have to say that after that, he became less and less angry and actually did apply the techniques we talked about. I think it mostly got better because his hormones calmed down.
I understand that SS are not able to do something urgently for him, but if indeed the main issue is his anger, could they direct you towards anger management classes for teenagers and maybe classes to help you deal with his anger better?
