I didn't think much about my health until this summer, you only know when it is too late (not that neither of us had any fault in being ill).
I usually get out of my self-pity by remembering my self invented maxim: There is always someone who has suffered more than you have, there is always someone who carried themselves with more dignity.
I made it for fun but there is some truth in it. I meet people who got along with under much conditions, and who carried the burden with out any whimpering.
I immediately thought of your guitar playing, but it is at least the right hand so you can use a guitar pick! Then I thought of Django Reinhardt
I actually feel lucky as my life has been pretty good and many people have it much worse. Django is an inspiration. I've played some of his tunes, but not got into the chord shapes he used. He had to adapt to having a lot less use of his left hand. I like the gypsy jazz stuff and would like to find time to study it more
