Is my girlfriend likely to die at any minute?

She has had a history of migraines in her family. Maybe even some anuerysms. She was epileptic. Maybe she still "is". But she hasn't had one for years. She's just turning 20!!! Was I stupid for falling in love with someone with a medical condition when I am this young? How can I live my life knowing that that is a possibility this early? I'm never gonna think that I'd date or love after her. If anybody says that I'll report your answer. But are we both screwed? I'd like an answer for someone with a decent knowledge of neurology. I think it was concluded that she has a weak vessel in her brain. Should I start a countdown or something? :(
