This.
This actually works for more than this sort of situation. It helped me become more social, friendly, and grew my self esteem. What seems to happen is that people seek out a situation for themselves that's out of their direct control.
So it can often help to fake being a certain way until people see you as such, and at which point it becomes easier to intergrate what you were faking into your own personality (Since your environment already acts as though it was), in this case; if people perceive you as out going, it will help you get out more. You're just gonna have to force it a little for the first little while.
