If there is any realistic possibility that you will lose your health insurance and access to meds, you really might want to concentrate on that.
I have been in a similar circumstance, I was trapped by a life I hated. I thought I couldn't leave this job because I would lose health care coverage. It wasn't good coverage, but I figured something was better than nothing.
It took some research but I found out that by quitting that job with lousy benefits, I could work somewhere I liked that couldn't offer benefits and get my health insurance via the National Healthcare Marketplace aka obamacare. I actually pay less out of pocket and have much better mental health benefits and access to care on that new plan.
Although it's not always the greatest, you might also look at Medicaid and see about qualifying for disability.
Who knows you might actually find yourself a better future?
