shattered, seeing someone having a seizure can be scary as hell for sure.

I have epilepsy, and had my first seizures in my early 20s. Back then they called them grand mals, now they're call tonic clonics. From what you described, that's what the woman was having. I used to have those back in the day too. They're all different types of seizures.....not just the one you saw. Although those are usually the most scary and dramatic.

But thanks to my anticonvulsants, they're under control.

It might help to educate yourself about epilepsy/seizure disorders. Take some of the fear away, especially since you have no history, and aren't likely to have one yourself. It would also explain what the woman went through, and knowledge could help take away some of the fear. Rational or irrational...fear is still fear and scary is still scary.
