Fragrance sensitivities

Im just battling with hr right now and trying to get a fragrance free ada accommodation for my very tiny workspace. They are denying my request but I'm really fighting for it. And before anyone asks or suggests pregnancy, there is no longer a uterus in me.

My 2 coworkers refuse to stop wearing fragrances despite knowing I have a sensitivity to it. Im kinda losing my mind. Wearing a mask does not help and there aren't many other places I can move my workspace to. I tried that yesterday but another person in a different department was heavily scented.

I feel really crazy right now because I'm the only person who is bothered by it. I'm a specialist in my field so I can't really find this job elsewhere or do it remotely unfortunately.
