Any chance you could rent a room in your home for a few hundred extra per month or supplement your income some other way, like picking up side jobs or selling something?

Or would there be less expensive therapy options to supplement your own, such as sliding scale at a clinic with interns or otherwise subsidized, so you could see the T you have once a month, and someone much cheaper another time per month?

I'm sorry you're in such a fix. I've cut back a lot too, though not as sharply as you and I have felt how hard it is to be crushed between life's demands and our own needs/wants.

P.S. You do not sound at all greedy to me, not at all. I do think it's going to be important to expand your support system to friends somehow though, but I do fully understand how tough it can be.
