I don't know much about toxic mold, but I know that people in naturopathy or possibly functional medicine believe they can do something about this. You should check one of them out. I don't know if you're open to this, but alternative health is really the road you need to go down, if you're trying to get help with something like toxic mold. Beth O'Hara is a functional naturopath with a website called Mast Cell 360. There is a section of her website where she talks a lot about the effects of toxic mold. I don't know if she would be outside your price range, but even if she is, there are a lot of other naturopaths and doctors in functional medicine besides her. I would check one of these people out.
Libbye I pray God will direct you to the right doctor that help bring healing and encouragement. We know "God specializes in things thought impossible. And He will do what no other no other power but holy power can do".
