I'm sorry your going through this. I don't really have an answer because i'm feeling the same as you. I wonder if i'm pushing people away. I think i am. Try to go back and remember conversations you had and what you said or if you return phone calls and messages on time, are you late when you meet with friends. All things that I have a bad habit of doing and probably because i'm a negative nellie and depressing. I realize why people stay away from me but it still hurts that they don't see the pain i'm in and at least try to understand me. If you can't think of anything then call someone up and just ask them? Couldn't hurt, just tell them you really want to know if you are doing something unconciously to push people away. Hopefully someone will be honest. Maybe its just them. That could also be. Anyway good luck to you.
