Have you checked into whether you are eligible for supplemental medicaid? It's called disability Medicaid here but there might be another program of Medicaid if your rent is so much of your income.

You pdoc seems really expensive; I see mine monthly for an hour minimum and even out of pocket it wouldn't be that high. With Medicare it comes down to about $30 per month.

But a good pdoc is worth a great deal. It's hard. I drive a long way for my therapist and the gas makes it expensive (even with reduced rate) and yet there is no way I'm going to change because he is exactly the therapist I need.
