My wife, son and I have had a weird experience like this. We were not test confirmed, but we are younger, so none of us had it that bad. We had a flu-like illness of coughing, tired, high fever. Then it subsided. Then a week or so later, I woke up in the middle of the night with shortness of breath. Felt like I had to mechanically breathe. Very unpleasant. Spent about two days or so like that, then was quite tired but could breathe a bit better. Then every week or so we will have another wave where we are pale, tired, headache and mild(er) shortness of breath. It feels like just recently we have come out of it, and we first had symptoms the second week of March.
