This one bear repeating - go to https://www.survivorcorps.com/ and find a long-haul rehab clinic or program in your area.
As to your fatigue, many of us with chronic conditions battle it - sometimes for days, sometimes for much longer. In 2017 -2019, I had a disabling case of pseudomonas plus MAC (mycobacteria aviums) infection in my already challenged lungs. It took nearly 2 years of multi-antibiotic "cocktails" to beat it into submission, and more lung damage occurred. At the beginning, a shower and breakfast were all I could manage without a rest. Over time I progressed, little by little, until I could generally do 2 hours of activity at a time. Now, nearly 4 years later, I can do perhaps 4 hours of fairly rigorous physical activity in a day, interrupted by short sit-down breaks. But by 4pm, my active day is DONE most days. To reach this point, I had to reach out to a pain doc, lung doc, ortho, my primary, and a miraculous PT. I learned when to push and when to back off.
This appears to be the model followed by the rehab program for Covid survivors - I'm sure it won't be easy, but probably worthit to get your life back.
Good luck to you on this journey - stay in touch with us at Connect, we'll encourage you along the way!
