All I can say is don't give up. My daughter finally recovered completely from CFS after 18 years! At about 15 years she was able to start work half time in a quiet low key office. Little by little she improved and went back to get a MS degree. Now, some 20 years after recovering, she had hiked the Pacific Crest Trail through the state of Washington, 268 miles. She regularly walks up to 6 miles. She was able to get a full time job and rose to be a very responsible adult in every way imaginable. The only change she has found is she is now allergic to several common foods. You might work with a nutritionist or naturopath to check that out. Again, Don't Give Up! You can't predict what your body will do, just as you couldn't predict how your body would respond to COVID. Take good care of yourself and let your body heal.
