You have an environmental illness and you react to everything. Lower your total load. All these things are related. Your immunity did collapse under the attack of long term yeast infection. It takes long time to recover your normal immune function.

You are being exposed to the Alternaria mold from somewhere either at work or home. 2 years ago I tested positive for the same Alternaria T.mold allergy and I didn't have any allergy symptoms or reactions but I had fibromyalgia, candida etc.

I got re-exposed recently after there was a leak in my apt and I cleaned up the area releasing mold spores into the air unknowingly. I know why I had that + result.Now my candida is much worse I have post nasal drip, dizziness and more brain fog etc. Trust me you are probably being exposed to chronic low levels of the mold. You need to get away from the source of the mold or have it cleaned up, then get rid of the fungus with anticandida diet, supplements and only then can you get better over time.
