This makes me very grateful that I had my first seizure as a kid of about 10 rather than as an adult.
Because I was too young to know any better, I was mostly frustrated by all of the worrying done by those around me. (I worried about the practical consequences like not being able to drive, but didn't feel afraid exactly.)
I did end up having a seizure disorder, but one that ends with childhood. I'm 17 years seizure free now and am confident they'll never come back. (That doesn't mean I don't have a moment of slight concern when some strange tingly feeling comes on.)
