I understand the paranoid part. I'm always paranoid that my friends would rather be friends with someone else or my boyfriend is just using me. The best way I know how to deal with it is to tell yourself to relax and look at the big picture. Is this really what's going on or is your mind up to tricks again? I don't know if that will help you or not but I figured I'd share what I try to do. It doesn't work for me all the time either. Sorry you're feeling that way!
