What's wrong with my son? is this a psychotic episode?

He cooks just be having a hard time. Maybe visit with the school and talk to teachers. See if people pick on him. And try to talk to him when he is not stressed or in his phase. If he is not hurting himself I would try to let him work things out. If not, try to help him. If he hurts himself take him somewhere to have him checked out.
