I struggle sometimes when I am tired.
Yes, it is a bit like hangman, that's a good comparison.
I've never commented about your stroke, it always felt too intrusive (or the danger of being facile about someone else's experience), even though you have been very open about it. Several people around me have had strokes, including my previous partner. It was very tough, but I read a huge amount about it, and about recovery and how long it takes, and although my partner didn't recover, I was heartened by the possibilities of recovery.
