Not covid for me, but around that time. One of the last things I did before I got sick that year was fly Covid patients out of rural areas. It was a very stressful time - especially when I was so damn tired all the time for no real apparent reason. Whatever, I'm on the mend now more or less.
I would go back tomorrow if I could, but I also recognize that chapter of my life is over, over 7000hrs is enough for one life time. But maybe I'll get lucky, and medicine will advance? I'm not holding my breath.
Reguardless, that's what I see, people grieving and being ANGRY because they aren't quite sure what to do with their newfound uselessness. I was that way for a long while. The feeling like you're not a part of it anymore, or that all that work and effort, was for nought.
But if anyone reading this is struggling with these sorts of feelings (like OP), understand that the experiences that brought you here, they are what make you who you are! They're a part of you! But they don't totally make you up. You should use your perspective to see if you can make even more crazy and creative and magnificent things than you ever could before! And most importantly, do it for you.
Society is really going to be totally overturned by this. The responses I see, the attitudes people have, a lot of it is stuff I just lived through a couple years ago. Good luck folks, you should probably go hiking more.
