@dabeaz I'm sorry. I totally get that feeling.
Not that you are looking for ideas or need ideas, but I always liked your music posts and about joining your city band (apologies if I'm getting the terms wrong.)
Pre-pandemic, I took three or four sessions of Ukulele lessons through our local parks and rec center. It was fun and it was a very enthusiastic crowd (over my fun level) but it reminded me of playing in school and college (non-string instruments)
