I'm sorry that to say this doesn't contribute much to the discussion but this expresses exactly how I feel when I'm introduced to new people.

I guess all I can say is don't do what I do. I.e. I withdraw and hide behind my computer where I can become "invisible" when I want to.

But I keep trying and sometimes I meet that person who can see what lies beneath and I gain a friend. When that happens, it soothes much of the preceding sorrow; it is really worth it to keep trying to engage socially.

I think you and I can eventually overcome all this self-doubt. I am pulling for you.
