You may be overdoing it. It’s not unusual for someone to start feeling a bit better, overdo it and then have a relapse. You may not have been getting enough rest and sleep recently. I’m convinced that frequent naps are essential to recover from an illness.
I can’t take naps. There’s nobody to pick up the slack. And then Christmas was upon us and all that stress. What a mess that was! The car died on the way to my oldest’s house. Limped it home and got the company van. $75 to fill the tank to drive two hours at 6pm on Christmas Day. But I got to see my oldest Grandson for the first Christmas we’ve ever had together. He’s 20 and his Mom kept him away. So the uncomfortable ride was worth it.
