Being independent from your family may require you to have some contact with others. As you improve your social skills and anxiety you may start to feel better about yourself and be willing to take a job with a couple of people around.

What about working in the back of a store, like in the stock room, so you'd be away from most of the people, or working a night shift somewhere, where there are usually less people around too.

Are you interested in furthering your education, because you can do that online these days, which could open you up to more jobs.

Don't be so hard on yourself - think of the things you enjoy doing and see how you can convert them into a career.
