Question about recovery

Hello all I am new to this page. I am getting serious with a girl who is epileptic; she has had been having some episodes the last couple days (for the first time since we are together) and I haven’t heard from her since last night (9 PM). It is now 1 pm the next day. She is always great about getting back to me quickly. She lives with her parents whom I have not met yet, so I cannot ask how she is doing. I am just very worried that something more severe has happened. Is it normal to sleep for over 12 hours a day or two after some episodes. Thanks, sorry if I sound ignorant I am very new to all this, but I truly care about this girl.
