I understand exactly what you are going through. I was severly addicted to the game called "Evony" and I would stay up 24 hours straight to play the game. Finally, I got tired of it and I also realized how much it was affection my life. You have to be strong and just walk away from it. I know it is hard, it was SOOOOO hard for me not to log on but I made it. Just have faith in yourself that you can do it!
