I became a first-time parent months after the initial lockdowns. And holy shit. In some ways, I feel like I lucked out (got to wfh, not much going on out in the world to miss out on, etc) while in other ways, the one-two punch of becoming a parent and COVID lockdowns basically ended my social life and spiraled me into some kind of Stanley Kubrik scenario where I felt totally trapped by domestic pressure and dead to the world. New parents probably struggle to hang on to themselves as it is, but in this case, the lockdowns leveled any part of my social identity not already completely pounded into the dirt by becoming a parent.
Luckily, 9 months in, I started getting mental help from a therapist. And many walls/monitors/guitars/etc in my home have their continued intactness to thank that for. Things have gotten a lot better, almost in direct relationship to me being able to say "enough is enough", take personal risks, trust my child to external care during the workday and some nights, etc... all stuff that would have normally gotten smoothened over much sooner, but thanks to COVID, took longer for us.
I've heard the same thing echoed from my therapist, and other parents. People have dealt with depression or dealt with kids who have become severely depressed (can't imagine being a high schooler virtually, I mean come on). I'm of the opinion that lockdowns and restrictions have done far more harm than good, and anyone who thinks I'm being dishonest on insincere about that opinion can go back to the early pages of this thread and read me taking the exact opposite stance in the early days.
That said, like others, still fully support masking (where it makes sense and isn't just a virtue signal) and vaccination (all adults should be doing it so we can stop this nonsense around subjecting it to the youngest of kids).
