Is there anything that you can take to help while you are stuck living with mold?

There is no visible mold and I live in my parents house, sick since i was a teenager and now too ill to even work or leave the very room which so probably killing me. I can’t spend time in the living room because of a loud refrigerator that parents reside to replace because they don’t make them that big anymore. I have severe ME/CFS and I suspect it and my long history of health conditions are all due to mold. But there’s just nothing I can do right now since none of it is visible. We’ve sniffed outlets and peaked in the attic but nothing. But my brother used to have a bunch of mold on his walls and I’ve had some on the ceiling over the years although it always appeared to be surface but I’ve got that under control for now.

So anyways because of all this my parents are not willing to spend the money on investigating the walls and even if they did it would probably be too expensive. So I’m stuck here I’m too ol to even go sleep outside or anything I’m so sick and every house in my city likely has just as much mold because it’s super damp here it’s a fog belt. So im wondering, is there anything I can take while still in mold to improve?
