Kimberley, why is it that no one trusts or believes you? What is it that you do that hurts those people around you? Is there some pattern that you can see in your behavior with people that pushes them away? What occurred just before your friend left last night?

I'm sorry that you're hurting, but please try not to be so hard on yourself. It's difficult for some people to maintain close relationships (for various reasons). Getting to the root of the problem is the first step in solving it. If you are in therapy, what has your t said about this problem?
