Okay...I'm talking about the future not now...
Major in web design, computer graphics, computer programming, accounting, or any business/secretarial stuff. There are loads of opportunities of telecommuting (working at home) with those skills. Also, if they offer a class in debate or communications do that. Something that will teach you the skill of talking to people on the phone.
These days, with technology advancing as fast as it is, there are lots of opportunities to work at home that didn't exist a few years ago. Another thought....brainstorm a list of things you'd like to do. Then go on the Department of Labor and read through what they call their Occupational Outlook Handbook...the entire thing is online at
http://www.bls.gov/ooh/. You can put in any job you can think of and it will tell you the skills you need, education requirements, demand for the job, work environment, whether it may be possible to work from home, and beginning salary. You may not be able to work at home the first few years; you may have to "get your feet wet" but there's lots of possibilities out there.
I started a support group for job seekers at

As for now...that's hard. You could beef up your secretarial skills, typing and such, and work in an office part-time. In an office, you'd have limited contact with people most of the time. I'd avoid fast food. Customer service of that nature is very hard for an introvert....been there/done that. A slower paced store may not be too bad though.
