Hey everyone, F 20 broke up with BF 21 about a month and a half ago, it ended well but then he did something that was just really dickish so we haven't talked since I needed his address to send some of his stuff back to him in the middle of May.  We're still friends on facebook and I went on his profile last night to see pictures of him getting all cozy with some other girl and it's making me wonder if he ever really did love me like he said he did.  I've decided I'm not going to let myself look at anything about him anymore because it just hurts too much.  

This brings me to my second problem: I slept with someone else two weeks ago, a friend of both me and the ex, and now that guy won't talk to me anymore.  I'm at home right now but my parents moved so now I don't know anybody here.  I'm stuck at home alone all day with nothing to do and I'm going insane thinking about how pathetic I am.  Can anyone help me/give me advice on how not to feel pathetic and undesirable and how to stop dwelling on this?
