Touchy?

Am I just a little down on myself or something? Sometimes I wonder if I just IMAGINE slights that people give me. Am I just so sure that someone is going to say something offensive that I make something offensive out of nothing? Why is it that I feel I'm being treated so unfairly and even rudely be everyone else? Is it all in my head? Am I really a bitch like everyone says? Really? Is it me? I do feel like people think it's funny to make fun of me, and I try to go along with it and not take it to heart, but it does hurt. Sometimes the jokes can go a little too far and people don't even realize they've hurt my feelings at all. Am I just being ignored? Do people just use me as a tool for their amusement and then not care about me at all?
