It occurs to me that you've applied the recovery lessons in an extremely controlled environment, and now you've got to step into the real world and where it goes from there.
I've started singing again after a number of years. It's one thing to listen to YouTube videos and read books that tell you how to sing, it's a whole other ball game when you finally do it. And for me, it's a pure absolute joy.
I've started hitting notes that I could have never achieved when I was younger. I yelp and enter "Peter Brady" territory during warmups, and I deliberately choose music that can send the neighborhood cats scurrying away. It took me thirty plus years to realize I was never going to get any better unless I embraced the ugly. And so I grown (kind of) to love those cracked notes and vocal skids. Embracing imperfection isn't a bad thing at all.
