I've been where you're at before bro. Get those grades up, discipline yourself to stick to a strict schedule, and eventually you'll find that you still have a couple hours for games. I'd recommend deleting the game and forcing yourself to stay away from the forums for a bit. After a month, or maybe two, I imagine things will start getting better. Anyways, take care, bud! We'll all be here waiting when you get back!

(Also hit me up if you need help in school. I'm in college so I've got much pro-ness.)
