When I didn't have insurance and we were barely making rent, I was actually able to get free T and pdoc appointments at my local community mental health center. I didn't even know it existed until someone recommended it to my husband for me. You could try googling "[your county] mental health" and see what comes up. You might have to make an effort to get into these places, go in person to find out costs and what they'd be able to help you with.

Good luck. Just keep trying. I know it's a hard, uphill battle, but you can do it!
