My father was epileptic; he was hit by a car as a kid and that led to brain damage and seizures for the rest of his life. He was on meds, but still had a few seizures each year. I had to know how to handle that since I was preschool-aged. How to call 911, tell them what meds he was on, etc.
I started having seizures myself in July, but they're only in my sleep. I don't have to worry about falling and getting hurt that way, but I still fuck up my ribs and back and bite the sides off of my tongue when they happen. My GP referred me to a neurologist in August; I still haven't been called back about that yet.
