Heartbreak

I just found out that the guy I like is now dating my best friend. Again.

I hate myself. This is just so messed up! Every guy I like, every time. He dates my best friend, and later on turns out to be a total jerk. But this one was different, he isn't a jerk, and he never will be. I'm just not worth it to them. To any of them. When I found out that he asked her out, I felt a really sharp pain in my chest and I almost stopped breathing. It just hurts really bad inside my chest. And I know it's not like, a disease or me going to die. But it feels really horrible.....
