EEG said epilepsy

This is all we have. Our 6 year old daughter was ill, fell over backwards, eyes open, for about a minute. We rushed her to the ER, they did blood work (normal), CT scan, normal. Pedi said to be on the safe side, we should do a sleep deprived EEG. I can't tell you how often I nearly called to cancel it. She was sick, spiking fever, she just fainted--that's what I thought. But a good mom checks it out, right? So we went ahead, and when the pedi's office called and said the report said our daughter had epilepsy, I just was in total shock. They couldn't tell us what kind or how severe or anything, just made us an appointment with a pedi neurologist, which is on Monday. I am SCARED! The only thing we can think of that is weird is our daughters' wild nights. She is prone to night terrors, or that's what we thought they were. I'm having a very hard time getting through the days. Our little girl is adopted, and all she needs is something else to make her feel different. I guess everyone thinks why my child, and I'm no different.
