Ovarian cysts and even just ovulation can tank your appetite. I mentioned my mold suspicions on the other thread, too, so I agree with WBF's cautions. Keep those items from your mom's in gasketed (weather-tight) plastic bins if you can, or at least tightly-tied trash bags, preferably outside, until you can process and clean everything properly for mold contamination. Books, papers, and clothes can't always be salvaged.
Assuming that AC just spewed mold all over your living space: Run an air purifier if you have one, and a HEPA vacuum. If you have rugs or comforters you can't part with or replace, then wash them and dry them in the sun for as long as you can. Encapsulate mattresses and pillows in zippered hypoallergenic, waterproof covers; that way, even if they're contaminated, they won't affect you as much. Dust with a damp dust cloth (I'd use vinegar) and throw away the rags afterward. Most importantly, keep the humidity level down in your space. If it's under 60% humidity consistently, then new mold spores that have been introduced (as well as old ones) won't be able to grow. It's bad news that you all three are having respiratory tract symptoms. AirDoctor often has coupons available online for 50% off their purifiers (so they're around $325) that filter to a size small enough to catch mycotoxins (most purifiers catch spores but not mycotoxins).
What kind of AC is this - a wall unit, or a mini-split? Wall units tend not to be cleaned and definitely grow mold, so if that's your AC, then I'd suggest buying a cheap window unit for this summer. If it's a mini-split, then I'm not sure the best way to manage mold, but I know it's hard without taking it apart completely, which voids the warranty. I'm sorry that your landlord is so unhelpful! Mold is so tricky to manage!
I felt awesome while I was pregnant, too - far and away the best I've ever felt.
