I've seen this exact thing happen with a facebook acquaintance. She already posted a lot about every problem she has on social media even before she got Covid, but with covid it was another beast. She tested positive before she got symptoms but before the symptoms even really began she was reading anything and everything in full blown hypochrondia-mode and getting more and more depressed and anxious about it (from what I could surmise from the editorializing she added to every covid related article or study she shared). Within one week of testing positive she was deep into the articles about chronic issues, so it was well before quarantining period was even over. It was pretty wild to observe and she's still posting stuff these days. It's hard to distinguish what is legitimate and what's for attention. While there may be legitimate issues, I can't help but think that it would be hard to separate legitimate issues from psychosomatic ones brought about by the way she dealt with it (and how it has become part of her facebook identity). She may be an extreme case, but I could totally see the same happening with other people to a lesser degree.
