People

It's really hard for me to believe that people actually care about me. Lately so many close friends of mine and people who I've been talkin to for years or for at least daily for a year or more than 8 months have been not wanting to talk to me anymore.
When I talk to people, I don't drag them down with my problems. I just have normal conversations and am so used to pretending to be ok. I know how it is to lose people for talking about my issues a few times. Even when they say its ok for me to do so, I do it, they get annoyed, and stop talkin to me.
Anyway, I just pretend to be ok towards everyone. There's no person I can just talk to and feel like I'm ok. Either they dont understand and I just have a fear of them leaving me. Everyone always leaves me in the end.
I really do enjoy hanging out with people. I enjoy having friendly relationships. But, it's like it doesn't ever last. Even the ones that I think are gonna last. I've been friends with some people for years and they just leave me. Idk whats wrong with me. I dont fuss or argue with people. I'm caring and considerate of other peoples lifestyle and feelings. I dont drag people down with my problems. I cant think of what I would do to make them all leave me.
Makes me feel like somethings wrong with me and I'm very careful of who I choose to call my friends. I dont just friend anyone. I just don't get it.
