@Cheesealicious I've seen covid trigger or accelerate dementia in older people. Lack of empathy is one possible symptom. I've seen this play out with several relatives, including my late mother.

I've also seen it change personalities. People being depressed for the first time in their lives post-infection. Even without that, a lot of people believe in a just world, and maybe the only way to reconcile with everything these days is to assume everyone deserves what they get?

I've gone no contact with an elderly relative who has become the worst version of herself, ableist and fatphobic, and seemingly unaware of how she affects others, in the last couple years. She's had Covid a few times, but is in her 80s too.

I wish you luck, and I hope your mom's situation isn't as dire as what I've described.
