Hi, I know a great physio in Midland, David Bryde, at North Street Medical centre. I know that is a fair way to go, but you may not need to see him all that often, and I think he might be really useful to you to guide you on your way.
David was a professional tennis player and he traveled with high-level sports teams as their physio. He knows a great deal about returning to full fitness after injury or illness. I drew on his expertise after 3 knee injuries in 15 months,(medial meniscus left knee, then medial meniscul right knee, then medial collateral ligiment right knee). I had no surgery, and no cortisone injections, but I had to do the right exercises regularly plus stationery bike at the gym to build up the correct musclesjust above the knee.
Unlike some physios who just seem to work on things with no particular clear stated goal in mind, he set me up with an ongoing process to get me back to full functioning with stronge healthy knees again over the course of a year. He also explains things very well, eg advised me to get a knee brace that did not fully extend and that totally prevented sideways movement because that would prevent further injury and speed up healing enormously..
He would be able to guide you in how to realistically work from being quite unfit and also quite limited by fatigue or whatever you are limited by. And to have a plan that helps you know how to decide what you can do on a particular day and also see your way to the longer term goal. He may also know about the type of exercise that would get your white blood cells and red blood cells production up.
Nice to hear you have weathered the journey ok. BTW, with friends can you tell them you want a complain session today, ie someone who can hear you complain for ten to twenty minutes flat and not try to brush it off, just listen, empathise and understand. When my son was going through a bad time he trained me to be his complaint-listener. But without training, I did not know that was what he needed. If you trust them enough, tell them" I know you are trying to help encourage me and be positive, but right now I need you to hear how crappy and scared I feel and how I miss the structures of my life I have lost."
best wishes
