It’s bad enough I hate my job but now I realize I’m allergic to the building (mold)

I was so sick all week last week at work. Sneezing coughing stuffy itchy to the point where I thought I had covid. Tested negative. Went home for the weekend and felt better after a few hours. Was fine all weekend including this morning. As soon as I get here it all starts up again!! If I ask my boss for an air quality test here he'll go into a bipolar rage! Help!?!
