My wife worked in ICU then COVID ICU. She still gets PTSD flashbacks from everything she dealt with when someone comes in with similar symptoms. I got front row tickets to seeing a person who's entire job is to keep people alive go from "oh someone I had today coded and we couldn't bring them back" every so often to "we had multiple people die today. A few more aren't much longer. If we put them on their back, they'll die. If we give them water, they'll choke and die. They still refuse to believe that COVID is real as they are actively suffering and dying of it".
Yeah, we get a touch testy when people say it was fake or overblown
