Thank you for going into this!
I've recently come out of several years of what you call "bad control and denial", and i'm glad to see the other side! I knew and told people i was diabetic but i just didn't care. Now i'm finally I'm starting to lose weight and i feel like i have more energy, me and my partner are hoping for our first child around 2022 so he's helping me work steadily towards that.
I'm definitely not the worst case out there, certainly not the best. No way would i be eligible, as it isn't affecting my life negatively apart from being a pincushion.
Interesting that you are also a pianist and struggle with motor control, for different reasons probably as i'm not on any other medication. When i play i sometimes get spasms in my arms, which causes my hand and fingers to seize up. It's the same at work when i use a mouse or type, although it's not constant. Just a violent twitch, sometimes 2 or 3 together. It's really affected my confidence with playing and i don't practice much any more because of it. I'm actually waiting for an appointment with a neurologist so they can maybe put a name to it and potentially treat it. I suspect dystonia, in part because the triggers i've found online are weirdly similar to what triggers it for me.
But i hope you keep on playing
