Welcome to WP!
You sound a lot like me. I too was diagnosed at 49 (and sort of over the shock by now), am retired from work, play the piano (take lessons from a Russian lady every thursday), guitar, drums and bass (and played accordeon and panflute as a kid), have two friends (because of their love for music, one is a professional drummer).
I like arts in the broadest sense (my mother was an amateur artist, I use to paint and draw and intend to pick it up again once I get my studio sorted) and dabble with photography.
I've never known romance but I've stopped worrying about it.
I hope you'll enjoy your stay here.
