I dont know what to do with him anymore.
He always had problems with friendships, and I never really knew why. However, I am beginning to see his behavior at home, and I can now see what the problem is. It used to be confined to school, and the school used to tell me about it, and tell me that they were exercising time out for him to go and calm himself down.
He is losing his temper several times per day now. Shouts, swears and screams out of control. Usually this is for minor things. His brother put his cup too close to 9 year olds cereal bowl. This was enough for him to explode.
His brother accidentally dropped his beyblade down the stairs, and he erupted.
He is walking around as a thunderous cloud, on edge.
I dont know what to do with him. I dont know how to help him, help our family. I cant cope with this sort of behaviour.
Other kids shy away from him, naturally, they dont want to be on the receiving end of this.
He is a very bright boy, and well cared for at home, he has everything he needs, but I can see that his temper is really ruining it for him. I try to talk to him about how his behaviour is affecting others, and ultimately himself in that others wont play with him, but he seems unable to control himself.
I am thinking we need to get a behavioural psychologist involved, but uncertain.
Or maybe we just need to move back to the UK where he has stricter boundaries and a more disciplined school. I dont know. 
Today is his birthday, and we have friends staying. They brought him fantasic gifts. Yet my son is walking around grumpy and tantrumming, muttering that this is the worst birthday in his life. It of course affects everybody. I dont know what to do.
