Today was my first day of the semester and my professor gave everyone Mazapan which is a mexican peanut candy. I have a severe allergy to peanuts and everyone was eating it in class and crumbs were getting everywhere and the smell of peanuts was STRONG. After the class ate the candy, we did a group activity where we had to put post it notes on the wall & write someone we look up to but everyone was touching all the markers and my contamination OCD kicked in. I felt uncomfortable and trapped so I asked to leave about 15 min early after explaining my allergy and my professor seemed offended and annoyed by that. I understand some people are uneducated about food allergies and how serious they are so I get why he was a bit confused. Was I just letting my health anxiety get to me or was that justified??
