Do something. Anything. No, playing vidya doesn't count. Get out of the house. Go for a walk. Go to a bar and have a drink. Talk to strangers. Start doing new things. Excercise, run, move. You are the only person that can cure it. Go pick a fight with someone. Go to the nearest big town you haven't been to and explore. Fill your head with new things. Just. Do. Something. Sitting on your ass and spending your time on /b/ isn't going to help. It isn't going to be easy at first, but nothing is. Curing a broken heart takes time and effort. If you really don't want to feel like that then you get up your ass right now and you DO SOMETHING.
