I'm so paranoid!!!

Hiya,
I am a really paranoid person. All of ym friends have said it and I don't deny it because I can see it's true, but I just can't help it. I form friendships with people but then after a while I just seem to think they don't like me-as in I see them giving me weird looks and just discard me with their eyes (if that makes sense). I know I don't imagine these looks but when I tell my close friends, they say I'm being paranoid, and I always think everyone hates me. I also think I am very ugly but when I tell my friends this, they're like oh no your beautiful, but i dont believe them!!!And then when I'm walking past a bunch of people, and they say something like 'oh her' I assume they're talking about me. :redface:
