You have likely been exposed to mold spores, fungal fragments, and mycotoxins, which have been somewhat contained without expression, until the triggering event, setting off the numerous symptoms you are posting.
The body has resilient mechanisms to keep us safe, however, a shock to the system (trigger) may act as a catalyst to completely alter this within a second!
I'm not surprised at all, since I myself have been through something similar, albeit with very different circumstances.
My suggestion is to seek a reputable Functional Medicine or Holistic Doctor to sort all this out for you.
You probably need a good detox regimen, a strict anti-fungal/mycotoxin protocol, treat locations of your body where molds/fungal organisms and bacteria are colonizing, avoiding exposure and foods containing mycotoxins . This would be a good start.
Candida is very suspect, something very few doctors investigate.
Forget the fancy conventional tests, which reveal nothing or even worse "erroneous findings"
I spoke last year with a director of a medical school, who admitted that Candida was not a condition included to any significant extend in medical school programs :( Seriously????
The symptoms you mention could all be connected to the aforementioned exposure.
Best wishes,
