Plumber came to the house to fix the bath tub, and I've been trying to be very careful about COVID but he didn't have a mask on. I was too nervous to tell him to wear a mask so I didn't, and now I'm worried that he has COVID and is in our house.

I'm trying to remind myself that it's going to be okay, and if I fucked up and brought COVID into the house, it's going to be okay. But part of me is really mad at myself for doing something so stupid. I could've just told him to wear one and say I have a cough, and just want to be careful, but hindsight 20/20 I guess... How do you forgive yourself and reassure yourself it's going to be okay, even if it seems like it isn't?
