I also don't think it's a good idea to make assumptions about how stressed or otherwise people have been during this period.
I have had a very stressful job, but unless you were very good friends with me (maybe 4 close friends and one group of 4 with one close friend in) you'd have no reason to know that I had been transferred to deal with Covid on top of my normal job for the duration.
You also wouldn't know about the support I've been giving to family members, and the stress that has caused. You might not know that my preferred form of exercise no longer exists as all the swimming pools are shut. Or you might not know I have asthma and am therefore twitchier about getting out the house, and that that makes exercise where I am away from home, alone, and have to get back (unlike a gym or pool where there are people around and I can stop and sit down etc, also no pollen, asthma exacerbated by pollen) more concerning for me.
Not all friends would know the above things at all. They might know one of them, very close friends will know all.
Plus there's been a pandemic, things are turned upside down. Lots of people who would normally walk or cycle to work will now be working from home. Lots of trips out with friends to go walking or walk into town no longer exist.
How does judging others improve anything?
