My boyfriend just broke up with me because he wants to be single. The problem is he was basically my best friend. I don't have a lot of friends and he was the reason I was feeling okay. But now that he is gone... I'm worried it will all come back. The insecurities and cutting. I'm not sure what to do or how to keep it away. At this point it feels like too much work to think about trying to actually get through it.
