@Windchime: I'm so sorry to hear your daughter is ill! This must be very frightening and confusing.
There is some good news, however. Febrile seizures are usually one time events, and not indicative of epilepsy or other chronic conditions.
Here on WiseGeek you can search for "febrile seizures" and find a useful article written by a colleague of mine. If you search Google for "febrile seizures" you will be able to find the Mayo Clinic's website, which is another great source of information written in plain, everyday language.
If the seizure your daughter had was a febrile seizure, there is only a small chance she has epilepsy.
If she does, however, have the condition, I can tell you it is a very manageable and treatable disorder with the right medications. My mother has epilepsy and she is a capable and successful physician. I hope your daughter is feeling better! --Sarah
