My GP tested me for Aspergillus antibodies and I came back very high. My GP remained open-minded and went along with treating me with cholestyramine (a binder that can supposedly bind up mold spores, according to the "Shoemaker Protocol") and I'm gradually getting better. My Aspergillus antibodies have dropped significantly. I'm functionally 80% better now but I still have a bit of a road to travel to return to how I was feeling before all of this happened. I generally avoid discussing this too deeply with friends because I know they would be sceptical (as indeed I would be if I had not experienced it directly).
It's difficult to explain how it feels to be in a situation where you've been healthy for your whole life and you suddenly come down with a whole host of symptoms in your late 20s for which doctors can find no biological markers. You get used to recognising the "internal eye roll" from doctors when you list your symptoms. It wasn't mentioned directly but you can tell they are dismissing it as either hypochondria or depression (I have no history of either and never even visited a GP before any of this started). The most positive thing that I can take from these last couple of years is that it has thought me a much higher level of empathy for other people and their experiences.
