I'm so sorry for what you are going through.
Other people have been in your shoes and have found their way back to health.
I had extremely severe candida last year along with mold problems. My immune system became severely depressed which is why I became susceptible. My mold was not an extremely toxic one but I had a severe mold skin infection and it was in my sinuses as well. I have not completely gotten rid of it, but I am much better and no longer feel like I am dying.
