I think you underestimate the quantity of people that don’t feel good about having to show up to work in person or take part in meetings or have to deal with in person social interactions.
Heck, in the grand scheme of things it’s more unusual to have to interact with tens of people you didn’t choose to interact with because your employer said so.
Am I? I mean I wouldn’t be able to tell, of course, but I find that hard to believe. I’m not particularly extroverted myself but it’s fine for me. The only reason my team doesn’t come in is because of the commute time. And we’re IT, not like marketing or HR.
Also “depressed” and “don’t feel good” are very different in scale.
