> when I got dragged into a project that was sufficiently interesting that I started overworking

This is what bites. I have some really narrow interest areas that I can end up being obsessive about, to my own detriment. We have to be careful.

Glad you didn't lose mobility and speech! I also feel lucky. I met others in neuro-rehab in far worse situations. For three months I couldn't walk and now thankfully do so with a stick and ankle brace. The hard stuff isn't the stuff you can see visually though. People see my floppy leg, and might presume that's the main thing, but nope. The big thing is the epilepsy, this constant monster present in the background. It's the invisible stuff that's often hard.
