not worry what others think of me

I’m sure most people don’t even acknowledge my existance but i still always feel that I’m pin pointed in a crowd. Like when someone giggles or something I always feels like it’s directed toward me or something. I always feel that after I talk to someone I don’t know, I think that they’re probably talking about me and saying how utterly stupid I am. I don’t like to talk about things I like in front of a lot of people becuase I think that later, again, they are going to talk about how my intrests are stupid or whatever. I really don’t want to be this way. I want to be free and not care what I look like or who I really am and I want morbidly to express myself and not give a hoot who thinks what about it.
