Yup...the first (and to my knowledge, only) time I caught it was when I let my guard down after I first got vaccinated and my roommates had a little get-together with people from a few different households without masking, testing, or any other precautions. Turned out to be the beginning of the Omicron wave. I'm just glad I was symptomatic right away so I didn't end up going home for Christmas and maiming or killing my parents.

[...] I'm extra pissed at myself for allowing the people who never stopped complaining about my choice to continue masking, to influence my decision about my health and my family's health.

This is the key bit. Those people who complain (and often claim to be worried about your mental or emotional health) are not going to be there for you or your family if you become (more) disabled or die, so fuck 'em.
