There are two completely separate issues here TBH @coodawoodashooda , aren’t there?
There’s your boy, who you know well and we don’t know at all, and competing theories from you and the school about what’s troubling him. That’s a big complicated thing for you to work through and nobody will be able to comment specifically on your DS, or whether he has autism or PTSD. So we are just trying to help with general information.
OTOH, there is autism, how it presents, how it’s best supported, what it feels like, what helps…and a lot of us here know a fair amount about that so feel qualified to contradict your “psychotherapy is as good as a diagnosis if you have autism” theory.
The two things don’t have to conflict.
I completely appreciate that you’re working your situation through, thinking out loud on the thread. I hope it helps.
But you will get a bit of gentle pushback if you keep insisting that we are all tackling our autism and our children’s autism in the “wrong” way and that psychotherapy is better than diagnosis.
