WEll, depends on how you define dying lol. Seriously. I saw similar things in my DS....personality changes, coming home and going straight to his room even when his beloved grandfather was here, short-tempered, prone to outbursts, constantly saying he was so bored at school, breaking down in tears over school - granted he was much younger than your DC --- all the while he had friends at school, teachers really liked and enjoying having him, but I had the refusal to do homework, etc.
