I went through this too when COVID first stated. I didn't know I had OCD then. I've always been obsessive about using hand sanitizer. When I worked as a cashier I couldn't start work until I made sure I had a bottle of hand sanitizer by my register. I would have people sneeze and then hand me their money. I would have kids (and adults) cough right in my face and the bathrooms were just disgusting. This was all pre-Covid. After COVID, I found myself spraying things like door knobs and light switches with Lysol spray or wipes. One of the reasons I didn't know I had OCD was because I thought it was just handwashing and liking things very neat and organized. But with COVID, I did do the handwashing thing for awhile. I washed to hands numerous times a day. To the point where they got cracked, red, and very sore. I would also avoid people in the hallway of my apartment complex. If there was someone else coming in or going out the same time I was, I would panic.
Wearing a mask was very hard for me. I constantly thought and felt like I was suffocating. There were quite a few times when I became very lightheaded and dizzy because I was htlypwrventilating under my mask.
