TK, the piano playing part jumped out at me particularly.
If you have the talent, and enjoy entertaining others, it would be a shame to stop doing that in your life. I know there will be other avenues to explore as far as that's concerned. Yup, playing at day centres for seniors - definitely. Or what about playing for patients in hospitals? Is that a thing? Could you do that? Or what about playing for weddings? That would give you some extra cash too. Or how about getting together with another musician, or a singer, and working on some repertoire? Maybe more than one musician, depending on what you like?
I'm gonna be working with a pianist on some classical (and a bit of easy listening and classic jazz) repertoire. It's something I've never done in spite of my training. I'm really excited about it though. It's going to be excellent for my self esteem (I'm used to being in the shadows, musically speaking). And who knows where it's going to lead?
Sorry for the sitch you're in. But I hope you can open some new doors to an interesting and fulfilling life.
