I work. I specifically chose a job that didn't require a lot of socializing. I prefer a very independent job. At the same time, it has gradually become more social with more employees and I have found it a great way to ease into more socializing.
There could be many reasons why you are having trouble finding a job. Are you getting called for interviews? If not, you might need to work on your resume and cover letter. Or, you may need to broaden your choice of work. Or, you may be in an area with a lack of available jobs. Whatever the reasons, find what you can do to change things, and try not to be hard on yourself. Finding work is difficult for most people.
If you are getting called for interviews, but don't get offered the jobs, you may need to work on enthusiasm. Most employers want an enthusiastic employee. I know it's difficult for AvPD, but you can practise putting on a cheerful person. That's what I do, almost like dressing up in a new personality suit.
What about data entry jobs? Something similar?
Getting a job can increase self-esteem, which can increase desire to socialize, which can make life better. Money is nice, too.
