I really want to help my son 
He's 8 and is on the route to ASD assessment ; although I'm certain he is autistic.
He has been acting out a lot this week (returned to school) ; he has angry outbursts , claws at himself (no damage done as he chews his fingers bare) and is generally shouty and upset .
Today he says he's so sad
he says his tummy hurts when he is so angry all of the time . I think this is down to stress.
I talk to him about his feelings but he can never explain why he feels like this . He doesn't know how I can help him and sadly , neither do I 
WTF do I do ?! The waiting times are so long I fear he's going to go without help at all anytime soon and it breaks my heart to see him so sad.
I can't get him to do anything without a big , distressing battle.
CAMHS won't deal with us because of the ASD potential .
If I were to seek private help , who would I see ?
A psychologist ? A psychiatrist? A psychotherapist to help him manage his anger ?
I'm at my wits end. Please help!
