I am really sorry, Amzi. I hope you continually improve.
To qualify what I am saying, I have had two major strokes and several minor ones. My vision's impaired, I have some physical coordination problems, am wheelchair borne, and have trouble with concentration.
Probably a big thing you will have to deal with is patience. One just can't do what one, formerly, could do and it's frustrating and depressing. For example, I haven't gotten better than Lesson Seven in Harold Mitchell's Book One (Beginner). By contrast, I could, formerly, play in Book Three with a range of Double High C.
I would say, one thing that might be critical to you is to get good and consistent physical therapy. And listen to your therapist.
Amzi, you might not recover at a pace you want. For those of us that had former lives being goal-oriented, it's a major paradigm shift is to go from blazing towards an end goal but to become more aware and engrossed in the process. You may have to go from practicing to play the Haydn to practicing for the sake of practicing.
At any rate, patience and optimism. Good luck.
