Went to the ER thinking that I had Covid, because I was getting short of breath with any kind of activity... not just strenuous stuff, but like having to sit down and catch my breath after walking down a flight of 7 steps. I expected them to give me a rapid test and tell me to go home and take it easy unless my symptoms worsened (because I felt fine at rest), but it turned out to be two large blood clots in both of my lungs.

While spending a week in the ICU, they also found evidence that at some point I'd suffered a stress-induced cardiomyopathy, which I have no recollection of but the first couple months after my husband died unexpectedly are all kind of blacked out for me.
