I am sorry to read that you are dealing with COVID but am grateful that you are sharing your experience on this forum. It feels like it the elephant in the room.
Hopefully, your next blood draw will show that your counts are improving. It may take awhile for your marrow to fully fight the virus off. I would caution you against returning to your normal workout routines until you are completely recovered from this virus, as you don't want to put unnecessary additional stresses on your immune system just to test things out. I only say this because I think that pushing through a virus was the cause of my AA. Just take it easy and slow.
Wishing you a strong recovery!
