Where can I find financial assistance for my cancer treatments?

At 54, single, no family, and unemployed after a 35 yr career as a paralegal, I was recently diagnosed with terminal stage 4 lung cancer that has spread to multiple areas in the brain. I am very blessed to receive charity treatment, but there are times I can't afford to keep an appointment or pay the utilities. State and Fed agencies all have told me I am not eligible for ANY assistance (medicaid, SSI, etc) because of the amount of my unemployment - which is my sole means of support. Having been denied disability, it was necessary to hire an attorney on a contingency basis, but as I expected, nothing happens very quickly with our government. My oncologist informed last week that she is looking into hospice for me, with 6 months at the best. I am having a difficult time accepting all that has happened so quickly in the last 5 months, and I get blank stares when I ask questions. Being independent for so long, it is extremely hard to ask for help - but at this point in time, I'm more than willing to BEG for financial assistance with co-pays and pain meds, but after all the rejections, I'm not sure there is anybody to whom I could turn. Have you any advice or recommendations, bearing in mind that 6 months isn't very long to find some relief. Thanks to all.
