I used to be like that, i was afraid to talk to people. Once i got into highschool things changed a little bit... well they changed alot. After i got a job at a fast food place, where i have to "deal" with customers, i feel much more comfortable with people. All you have to do is, really, just suck it up and do it. I know that sounds mean, i don't intend to be, but just jump in.
