About Affordable Health Care?

I am a 57 year old woman, diagnosed almost 14 years ago with breast cancer. At that time I did have Insurance that covered the cost. But with-in a few years it became so expensive I couldn't afford to keep it. When I tried to find another Insurance, no one would take me...they would hang up on me when I told them breast cancer. Now, I have been with out ins. for many years, Thank God nothing has been serious for further treatments. I have paid for my mammograms and blood work out of my own pocket. Now at 57 years old I got my CDL drivers license to drive a school bus to get health insurance. I do have my own small business for 30 years, I do not have any employees. Paying private Insurance is very costly or the deductable is so high, I can't pay it. I did not ask for Breast cancer, seems I'm being punished for this!!!!!! I was only 43 at the time, I have one daughter that I thought I would not see her grow up. I work everyday to pay the rest of my bills, groceries, etc... My mammogram and blood work was due last November, this time I can not afford to go get this done. Can not apply for Medicaid, between my husband and I, we make alittle too much. I'm really getting scared for my life at this time. I really do not know what to do, but wait on my Big Yellow Bus to drive those precious children to school. Please Please if there's any help for me out there, let me know....Thank you Cheri Miller
