Timeflight, Bless you. Please don't give up. I too have long Covid and just got a diagnosis in early May after having it last year. I had almost identical issues to yours after Covid. I got an echo/stress test done because my heart rated stayed in the 130's and I hurt in my chest....doing nothing it was still high. My heart was fine. This lasted about 2 months and then my heart rate came back down. Even walking to the mailbox was exhausting. I know you get it. The brain fog was terrible. I couldn't find my words. That got better as well. Make notes and post where you need to of reminders to yourself. I have never been so exhausted in my life as when I had Covid. I felt "lifeless" due to the fatigue. Rest is healing with Covid. Do a little something.....rest. Your body needs it. I am so sorry. I empathize. This virus is brutal to some folks like us....not so much to others. God Bless you. Praying for you.
