I had a really bad patch a few years ago and was technically homeless and unable to work in a structured setting due to my mental state, so I started freelancing but it took a long time to get off the ground--years, in fact--but I found early on that I could housesit and pet sit to earn food money, while also doing my other work. I took anything offered--started out with $10 a day to look after someone's cats and then was able to get more substantial and regular housesitting arrangements so that I basically had a place to live, just in a different spot every few weeks or months. But I could continue to do my work as it built up.

I had no insurance and no way to pay for therapy, so it was just not something I could entertain. In your case, I imagine if you told your therapist you're dumpster diving for food, she knows you're in financial straights. $15 per session is pretty awesome, even in your situation. That's why I suggested the pet sitting or house sitting. A little of that can pay for your therapy and food--assuming your freelance work is such that it can travel with you.
