wow, didn't see the article, now that I can be somewhat sure it's true- (and if it's not, oh well, let him have some attention it won't be the end of the world.)
again, really sorry that this happened.
But seriously, can't stress it enough, find some friends, if you don't have any then make some, and talk about it. Sitting at the computer will not help. During school or lunch or during a project or something like that, find some time and talk to somebody about it. Tell your mom, "I need to talk about it" or something like that, I have no doubt that she cares more about you then about WoW. Trust me- being alone, at a computer or not, never makes me feel better about anything. If anything it makes it worse.
