I struggle with the isolation also, but in my case it is a bit self-inflicted. I have fear of reinfection, so avoid indoors - no bars or restaurants. I will go indoors to a store or pharmacy on occasion but wear an N95s. I mask at my doctors office though no one else does, not even my doctor or medical staff. So yeah, it’s like living in a different world. And yes, have lost friends who think covid is no worse than a cold. It’s a tough spot to be in - everyone else has moved on, but I’d still rather be safe than sorry.
