Well it's really not that easy to just quit WoW, I have been playing for five years. Also, read my last post.
I'm really sorry to hear this. You story made me cry. I feel sorry because I simply can't help you anyhow.
I'm very sorry for your loss, and even sorrier that I cannot help you with this challenge. Sometimes, you just have to put one foot in front of the other. It gets better. In answer to your OP, I also would rather play games and watch ponies than do homework or study. Sometimes, I do slack off. But my dad is a bit of a jerk about things like that, and comes after me every hour on the hour to make sure I'm doing some sort of work. In some ways, I appreciate it, but in other ways, I hate it. Truth be told, he's hammered into me a sort of work ethic where I can only go for so long without working on something challenging and productive without feeling useless. I might not be able to relate to you completely, but your feelings are not wrong. You're going to be okay. I know it from a different (yet also related) sort of personal experience. It gets better.
