In March of 2020, we all started working remotely and I haven't seen any of them since. Even if I wanted to, almost all of them have moved to other cities, states, or countries. Most left the company we were at (including me). We have a Discord server where we all still talk and chat, but it's a cheap imitation of what we used to have.
Now, I work with a team of people who are completely scattered geographically. Maybe once every few months I will see one of them in person if they happen to be in the area. They feel like strictly co-workers- I don't think we've ever really laughed or just goofed around that much, and certainly aren't hanging out outside of work hours. I wouldn't be able to call one of them up in a time of crisis and ask for help.
I miss my friends, and the simple solution would be "go find new ones!" but, like this essay points out, that's not exactly easy and there's a "blind spot" about how hard it can be. There's also still a pandemic going on- I haven't caught COVID-19 yet and don't plan on it. Any sort of friendship that would involve physically being near other people on a regular basis is just asking for it. To me, getting sick is not worth having a friend, even though it is wrecking my mental health. I know that equation is different for other people.
