Yikes, well sounds like you have been in a bit of an epicenter for COVID.
Every single person I know who has gotten the virus had the smell/taste thing and some fatigue, that was it. We all have had different experiences. Based on mine, your infection sounds like it was really nasty. Serious breathing issues is a major complication.
We did have one distant relation who was very, very ill with heart failure and cancer die with COVID as a complication, but he was in really bad shape already.
