You should sleep well. This enemy is not going to break in overnight. You have under control what you can control, and it's plenty! Certainly, be at peace with that. I'm glad you aren't stressed.
I've heard from a few people freaked out, yet, frequently going here and there, gotta get this, swing by there, couldn't find this so went to 3 stores looking for it... and oh my, isn't this scary??
Well, sheet, yeah, if I were running all over town shopping all the time! I am fortunate to not have the shopping gene, but even if I did, holy moly, I'm pretty sure I could stay put for a while. There are few things that are so essential that I would go to three stores looking for it. It wasn't until I was on my last roll that TP was going to become essential, and I scored first time. Luckily, long past the original run on TP. I would have come home with what I did find and deal with it another day at another store. One exposure is enough for one day for me. Or, heh, one month.... I'm not greatly concerned, but so very not interested in pneumonia, or sickness at all, that I'll take sensible precautions.
I'm more concerned for others than for myself. It's getting harder and harder to handle the death toll, I find that stressful. So I try not to dwell.
