I was talking more about your education - do you have any college or university? If you don't, you could try to find something at a college or university to do... and look up distance/online courses so that you can minimize the time you would need to be on campus.

You could try and do some form of environmental work in a park. A lot of factories require minimal conversation although you would have a lot of people near you. You could get some form of computer science degree and try to find a job that would allow you to work from home. You could try and get into a trade like plumbing, where you'd interact with people but really not all that much. You could get a job at waste management and be a garbage truck driver, where you'd only have one person. Maybe a job at the postal service if you could be out delivering?

What are your interests in life? That is a good spot to start when trying to figure out what you would be able to do. The more you like the job itself, the easier it will be to tolerate and get used to any interactions with people.
