I actually do understand, just maybe not as much as you want me to. I used to be pretty deep into the miniatures scene, Warhammer 40k to be specific, and I met some people with Parkinsons and maybe MS that said painting miniatures was both therapeutic and for some healing as well. I'm not telling you to get into a game that you can't afford, 40k is intentionally expensive, but perhaps picking up a hobby that is conducive to your disability may help. And if you wanted to share your progress here in the off topic section, or anybody really, I would love to see how whatever new hobby you pick up helps you progress. Just know that with painting miniatures, don't expect to be good at it. I don't have any disabilities, and I was awful at it at the start, but I eventually got to the point where my models impressed many of the people who saw them, and I don't think they were being placating with their remarks. So if you need any intermediate level pointers, I could try to help you out if that's the route you decide to take.
