Bipolar and Health Insurance cancelled

I'm bipolar and my health insurance was cancelled
I just found out wednesday last week 5/6/09 that our health insurance has been cancelled and Cobra was not even offered. It was cancelled without notice on 2/28. We do not qualify for Cobra as the company has less than 20 employees, we do not qualify for Adult Basic because we make too much money per them. (unbelievable). No one take into account your living expenses when making a determination on qualification. Does anyone know what I can do now? I need my meds or I will get sick again. The county says we make too much money for medical assistance, cause they consider us "not below poverty", but they don't know our situation. I have considered private insurance, not that I can afford it, but most health insurance companies are not likely to take you with "pre-exsiting" conditions. We are on the brink of losing everything. Needless to say, currently my mental health is not stable. Any advise would be helpful.
