I hope you find a way to get the care you need. Is there a self-help group in your area that can atleast help in some way. The county mental health services offers some type of therapy. Group therapy is cheaper than individual counseling. Can you make use of your agency's group therapy? A lot of agencies do have a sliding ruler fee schedule. You might look into that. I am surprised at the rate that you are being charged. I have a disabled friend who pays a very small co-pay for therapy/ the physchiatrist that he sees. Is there another provider that doesn't require the extra $50 dollars?
I do find it amazing how much it costs to talk to a T. Hope it works out for you.
