Frouke,
I got covid last January 15 if you don't count the 10 day incubation period. thought I recovered well from covid as of early February. I had a great deal of energy and could return to the gym. On Feb 17 my heart rate soared to 148 per a doctor present who happened to have his bag when I collapsed at church. He immediately called an ambulance and I was in the hospital for 3 days, I've been tired ever since. I struggle to keep my house clean, meals cooked and lift a few weights at home. I had been used to walking with vigor 45 minutes per day as well. Now all is a struggle. I walk slowly and lift far less weight at home.
Every day is a challenge. I fight my way through them.
