Job advice? (Not baby-related)

I'm in a bit of a pickle here, and I'm hoping for any input as to what I could do for work.

Currently, my husband is the only one working. I have PTSD, panic disorder, bipolar disorder, and some yet-to-be-diagnosed chronic pain. So it's hard for me to find a job I could function well in. So we have already just accepted that I would always be a stay-at-home mom, and he would work. But it has always made me feel absolutely worthless that anything I want or need has to be purchased with money I did not earn and don't really deserve. It also would be nice to have a little bit of extra money to help us pay our school loans faster.

Basically, I need any ideas of jobs you think someone in my position could do well in. My main issue is that I can't work with a lot of strangers all the time, which most jobs require. And because of the chronic pain, anything that requires long periods of standing wouldn't be good. I couldn't finish college, so I only have an Associate of Science.
