I'm so sorry to hear that. Please don't give up!!! If I were you, I think I might try contacting Andrea Roane of Channel 9's Buddy Check...

If nothing else, maybe they would do a story on the injustice of proper screening/medical tests that are necessary, but can't be performed because of insurance!!! Heck, write your congressmen! Maybe Barbara Mikulski would be able to help somehow?? You would think as a woman, she would have a vested interest in this type of thing?
Senator Barbara Mikulski: U.S. Senator For Maryland
Heck, you might even want to contact Oprah... Seriously! There has to be somebody out there who can help.
Good luck to you, and I will be keeping you in my thoughts and prayers!!!
