Oh my. Oh dear, that's hard. My condolences. I remember a classmate dying and playing Tetris alone in my room for a few days seemed to help a lot. If I were you I would watch sad movies, if there's any chance you can visibly cry over them. Also, physical exertion to the point of exhaustion then a good sleep (think swimming all day)is the best way to balance the overexcitabilities, i think, or structured and scheduled yoga classes work well long-term (karate ?)I would take the kid to the whole funeral service. Since you're Christian I'm sure your pastor has had training in counseling. Maybe your son wants to talk to one of the ladies from the church.
There's a lot of good medicine in fresh air and sunshine. Send him out in the yard. Those are my thoughts. Again, my sympathies.
