@leahdrose, Welcome to Mayo Clinic Connect. Twenty years sounds like a long time ago. In fact aroujnd 20 years ago is when I was diagnosed with my liver disease (PSC) that was progressive and without a cure. I can really understand how you must have felt with all of the 'helpful' suggestions from family and friends. I had the same experience with advise from well-meaning friends.
You are absolutely correct that your body is still adjusting to the immunosuppressant medications, along with continued healing and gaining of strength. It sounds like you have a good relationship with your doctor who is leading your Covid19 vaccination schedule.
Are you comfortable with getting outside and getting some exercise? Now that, I presume, you are feeling better, what are you doing with your time while being safe at home?
