I have so many materialistic needs, so I really need to have a job. I quit my first job, mostly due to social anxiety issues and after that I was really close to becoming a "hikikomori", but the need to have money for cars etc, really forced me to seek another job. Then I heard about the process industry, where people work in shifts 24/7 and they have lot of day offs... So I somehow trained myself in night school for that profession, applied and got the job in oil refinery. Work itself is really difficult to explain, but most of the work is just surveillance typed and independent, so I manage to avoid social interactions pretty easily.
Best part of the job is the working schedule; 12h long shifts, 2 day shifts followed by 2 night shifts and after that ~6 day offs. (three more days and I have actually 10 day offs) That's only 12 work days/month and has literally saved my life. If I had continued that 5 days+weekend off schedule, I would have killed myself already. Sure the days are long, but so many rest days really help ease off the anxiety.
If you think you can cure your social anxiety by forcing yourself into social situations at work, then this kind of job is probably not good for that, but I personally tried that "exposure therapy" for couple of years in my last job and rushing back home from work to cry in my bed every day was enough for me. I'm not saying that doesn't happen anymore, but it's not as common.
