Asthma, allergies and mold, OH my!

Has anyone suffered from seasonal allergies only to get worse? Then find out you have been exposing yourself to mold?
For the past few months, I have had a multitude of seemingly non related issues. I found out on the weekend that the carpet in the basement hallway in my apartment building has a growing mold spot. Washer and dryer are on basement level. I also take care of neighbor's cat, lives on basement level, while he works out of town. I blamed my symptoms and painful lungs on this cat. Has anyone had to deal with such an issue? I am not able to move. I made a maintenance report. ( just have to wait for response on actions).
I have begun to wear N95 masks any time I need to leave apartment. But somehow, I still am exposed. I want to try and be able to not have a severe asthma flare up. Funny enough, the flare up I am experiencing is only mild right now. But every passing week, my lungs are protesting more and more. I have an appointment wirh my GP soon. Lord! I hate the waiting game!
How have you been able to cope without moving? I think it still gets into my home on the second floor. Everyone's experiences welcome!
(If it were up to me, I would rip out all common area carpets!)
