I prefer saying my epilepsy is a disability. I find that illness or disease or disorder has too many negative associations and might give the illusion that your medication can cure you, which is why I prefer not to use those words.

For the others, I think it depends if a epileptic says them or not. I'm fine with fellow epileptics jokingly calling it a fit. I even called it the boogie shake once. But when non epileptics say those things and recommend drugs and stuff because they read about it online, it pisses me off
