It sounds like your parents are looking for reasons to kick you out. Housing insecurity is a huge stress which can damage your health and shorten your life.

That's a hell of a lot of pressure. If you don't mind my asking, what type of meds are you taking? Some of them can be superfluous and causing your problems. I know two people on Adderall who turned into fucking monsters, and had no memory of how scary they got. When they got off that shit, they became normal, sane human beings again.

Some "therapists" are simply in it for the money and hand out pills like fucking candy. Mind you, if you're talking about something like Serotonin reuptake inhibiters, that's a whole different ball of wax, and suddenly not taking them can make you quite dead.

If I were in your situation, I would set up a gameplan for getting my own place within a reasonable timeframe, and discuss it with my parents. Don't take shitty jobs you'll hate the rest of your life though. Get work that affords you a reasonable amount of self esteem.

Healthy food, regular exercise and adequate sleep can do amazing things for your mental well-being too, by the way.
