Mold

I’m not sure where to post this… A friend of mine is letting me stay at her house for a bit which I’m super grateful for, but the thing is I’m in a moldy basement. My stuff is getting covered in black mold. I’m feeling sick all the time, tired. Hard to breathe even when I’m not in the basement. I have a mild headache all the time from the mold, mainly in the morning and before I go to bed. I’m trying to formulate a game plan to limit how much time I have in this situation. If anyone has any advice on how to deal with the symptoms of sleeping around mold every night, please let me know. Thank you.
