It wasn't a group of people, but rather individual friends which I lost one after the other. In the last two years, five friendships have ended, all of which were about five years in duration. Separate from this there are friend groups which I simply grew apart from. I was unable to show any of my friends that Covid was a psy-op and this was mostly an issue for me. A friendship feels superficial for me if we can't even agree about something so fundamental, so I retreat. There was only one friendship that explicitly ended because we had a fight about lockdowns. The other four individual friendships ended for unrelated reasons.

Which is not to say I'm lonely, by the way. I made other friends, both offline and online, and this is never a problem for me because I socialize easily.
