Chlorine dioxide kills off mold and mildew. It can, in spite of being a chemical, help people who are sensitive to chemicals.
The process is involved.
I would suggest that you start with your room. Mix up a dose of Miracle-Mineral-Supplement and put it into a bowl and set it on a shelf of your room. If you can detect the chlorine dioxide odor, the dose is too strong. You should just be able to every once in a while catch a whiff of chlorine dioxide and no more.
The next step is to disinfect the AC vents, and then to work your way around the house.
If you run into areas where mold is growing, you need to clean it up and address the cause. Chlorine dioxide will kill the mold, but it will not cure the problem that is causing the mold in the first place.
Once you have everything under control, your immune system may kick in enough to protect you from future problems. At this point you can address your illness and go on from there.
