I've Spent My Entire Life Feeling Overly Self-conscious And I

I've spent my entire life feeling overly self-conscious and I also have a lot of fears, especially in social situations or when I am looked at or feel I'm being looked at. I also have this very strange thing I do where if I talk to people, in a group or one on one, I always feel like I talked too much or that people just aren't really interested in what I have to say. I ALWAYS tell myself that I just shouldn't ever talk. I actually get tired of hearing myself talk about anything......as if it's just not worthy to be spoken.
