Susie,
I am not 100% sure about this suggestion, because different states have different laws on what insurance companies can and cannot exclude, as well as on pre-existing conditions. I am in Michigan, and I know that BlueCross/BlueShield do extend coverage to people with pre-existing conditions. It might be worth your while checking with them.
I know a friend who is licensed with BC/BS, I can ask him for you to see if it might be something you can fall back on. Again, I am not totally sure, but I have good feelings that it might be a solution for your concern.
