Learning Points: He stays in his room and refuses to go to school

My 13-year-old son has changed a lot in the last year. He was always easy going and had loads of friends but now I find he doesn’t want to go out and spends far too much time in his bedroom. He also tells me that he is anxious and he has recently stopped going to school.

He is very irritable too. I really don’t know what to do, I’m afraid if I force him to go to school I’m doing the wrong thing but I have to work so staying at home is not an option.
