I feel for you. When I have to go for groceries, I wear an N95 mask plus vacuum fitting swimming goggles. And nitrile gloves. On my head I wear a stocking cap. When I get home I take off those clothes in a special room while still wearing my mask and googles. I take off my clothes very slowly in case there are virion particles on them and they go in a special hamper to be washed with Lysol laundry sanitizer. These are just SOME of the things I do when I go out. Just some . . . . . to give you an idea.
I am in a high risk group for being hospitalized and losing my life to the SARS-COvid virus. So I don't think being super careful is unwise or abnormal. The 30 trillion or so cells in my human body depend on my brain to keep them all healthy and I think my brain is doing a pretty good job. Of course I have been vaccinated and received my booster shots. Best to you!
