I got very sick in Jan and February of 2020. Covid was not "a thing" yet so I don't know if it was covid. I have had chronic fatigue since. My school closed for COVID PANDEMIC IN March 2020. So I finished my teaching career "online" and then retired that summer. I helped my daughter by supervising 3 children in their online school year at home...while m6 daughter went to the school to teach her 2nd grade class online. I was healthy enough that year. I got the Covid vaccine in January and the booster in February 2021. The school year went by without incident.
