It's causing a lot of stress when I get back home. Wondering if I somehow inhaled it from someone, only feeling relief many days later when no symptoms developed.
I feel the same way too and I'm paranoid already to the nth level when I leave home.
I basically do my weekly groceries to restock on our basic essentials at home, although I'd much prefer to actually do it once every 2 weeks instead. But more often than not, it's unavoidable and I just need to do my very best to avoid myself from catching anything.
