Breaking up

Aw man...Long time no see. it's been a depressing last couple of months. I was recently dumped wit a girl I really liked. Not gonna talk about what happened, but its hard to get over it. It's been nearly three months when it happened. What sucks is I still miss her her and no matter what I do, I can't get her out of my head. Trying to keep myslef busy or else she pops up in my bed. What's worse is everywhere and everything I do there is something that always remind me of her. It feels like a big chunk of me is missing. Anybody got some advice for me?
