I relate to your post, especially with the social part of life.
I made a new year's resolution toget out more, and i started today by turning on my facebook. Im 26 years old and don't want to be at home all the time when im not at work or school.
Socializing overwhelms me easily though, so i think what i really need to work on is setting a good balaa between too much and too little stimuli.

feel free to pm me if you ever need to talk.
