I feel you on this. I was locked up in a hotel with SARS-COV-1 (2003) for three weeks. No one at the time knew about this bastard of a disease at this time. My running jokes now that you unfortunately experienced it was ...
Remember Homey the Clown from the 1990's In Living Color with his sock and ball he would hit people. Well that happened every day all over my body. Then bring someone with a baseball bat and have them hit you in the chest non-stop.
If I wasn't asleep, I was wishing for death over and over. I then caught MERS and I felt it coming on. I just couldn't do a hotel for weeks again and I went home. It hit hard Thursday morning. I moved my flight up to Friday Morning and warned my partner I was Sick AF. She used lysol like it was a fogger, and there were times she thought I was dead in bed.
I was sleeping 20 plus hours a day.
It is why I have zero empathy for anti-vaxxers.
You are 100% correct. You have just got the mother nature booster shot. Just work on healing since as you have seen it will take time to recover from the hard hit you just took.
Be well and get healthy!
