A woman I know (early fifties, no co-morbidities) was socially active before covid. She hasn't left home since March 2020.
She has refused to see anyone indoors (apart from her husband) since March 2020.
She will only see friends if they agree to take a covid test before visiting. She then expects to sit with them her in her garden (socially distanced, of course and in all weathers) and asks them to bring their own refreshments, cups and plates. She wears a mask in company and expects her visitors to do the same.
Living as she does, she has very little conversation apart from how irresponsible most people are for not testing frequently and not isolating. "Covid hasn't gone away, you know", "People should be wearing masks", "The government should be doing more to warn people about the dangers"...
As you might imagine, very few people have bothered to stay in touch as the years have passed. She succeeded in keeping her husband in isolation for a few years, but he became increasingly fed up and left a couple of years ago.
Her father who she hadn't seen since early 2020 died last year. She refused to visit him because it would be "dangerous" and "irresponsible".
She was a nervous and anxious person before covid, but never to this extent. Covid and the campaign of fear around it has ruined her life.
