I can\'t stop thinking!

I am so afraid of it all, this talking to people! It really scares me, I wish alot that I was someone else, but in the end I know I would still be the same person in the end.You know it frustrates me so much that I can't talk to guys, it makes me feel low! (but then I can't really talk to girls either! But I can talk to them more easily than guys.) I just don't know what to do, I can't stop thinking about absolutely everything! It's really killing me! Because I really want to achieve my goals so much!
