I'm sorry your going through this op. Sadly I got ripped apart on MN when i posted the same thing . Its great that you are getting very good advice and hopefully there's more understanding of child to parent violence.
My ds was a little older 16 so in some ways little easier. I did kick my ds out . Because I could not cope anymore and the effect it had on my other children he stayed with his older sister for a while.
We did have a social worker for a short while . She did piss me of because she was going on about things not realivent like our dinner routine. I was like my son is violent and you want to know our dinner pattern. I was plunt to her and her manager . And they backed of us as a family but gave DS his own social worker. Which was needed .
We had a referral to CAMHS but they did reject. Sadly it was only when DS tried to kill himself that they suddenly wanted to know. DS has done alot of work with CAMHS he was seeing them for a long time . And did alot of work with them regarding his mental heath. He's still under CAMHS but at more arms length.
I done a course that was for parents of children with emotional dysregulation. Although the problem was with my son and not with anything I had done wrong . Doing that course did make me feel heard and that I was not the only one going through it. It also explores different ways to parent. Things like picking your battles. That taking their Xbox away is not always the best thing to do if you have a violent child. There were lots of things to be honest . But it did help..
Education wise I deregistered ds . He's was also meant to be home educated. But that was impossible. But im hoping he will want to continue his education at some point.
Ds is in a much better place now . The violence has stopped he does still have mental health issues that are complex. He's in supported accommodation but still spends alot of time at home . And ges much more pleasant now . But hard work also . Hes soon to be going into semi independent living for people with mental heath difficulties .
So things can get better . Not sure if it was helpful to share my story . But please except any help offered . Even if it is a parenting course do it anyway my its something for you . For you to feel heard and you can explore things m I hope things get better for you soon 💐
