whats wrong with me?

I I'm still feeling like crap about myself. I have no friends to call and talk to. They all have boyfriend and baby's to take care of, it makes me sad that I'm alone I wonder if I'm going to meet someone that wants to be with me.I so scared of getting hurt I still miss my ex. I wish that he would call. I'm so stupid he is not think of me and I'm here crying over him that why I hate myself I cant do a damn thing right what is wrong with me why cant I keep a guy?
