Perhaps missing the obvious, which is that a lot of people did get sick or die due to covid, and quite a number seem to have persistent symptoms after the fact. It would be odd if that didn't lead to stress. I'm a bit doubtful on the social isolation explanation, simply because we have a control. Some places never really locked down, or did so for a very short time span.
