I don't have a job. ... I live with my parents, who support me, and rarely see anyone else in a social context.

I really would focus on these major problems before spending time on running from pond to pond with a measuring tape (or figuring out which raiding guild to join).

When I start looking at job postings, I freak out

That's a problem you have to fix. Not knowing you I cannot offer any advice on how, but I can predict with high confidence that your success in solving this problem will have a major impact on your life.

I also have no confidence in my ability to get and keep a job in the current economy.

You don't know until you try. Also, since you have no job at the moment, your downside is zero.
