Advice please.

Hi. My name is Candace. I'm a 36 year old single mom. About three years ago I started having these episodes. I call them that because no one was around, I couldn't remember anything and had no idea what happened. The first one was at work. My coworkers found me outside staring at the sky and unresponsive. A year later I was at work and was found in the floor unconscious with my head busted open. A month later I was found at work again unconscious in the floor. The only thing I could remember was feeling this weird panicky dejave right before the last one happened. After seeing a neurologist I was told he didnt know what happened and that was it. Another year passed and two weeks ago I had a seizure while asleep. I know it was a seizure because my daughter witnessed it. I work anywhere from 55 to 75 hours a week and get very little sleep. The ER doc said he believed sleep deprivation, stress and exhaustion were the cause. I've been reading everything I can find on seizures and am currently waiting to see the neurologist again. So, I guess I'm just here for advice or answers or anything. I know only my doctor can tell me for sure, but does this sound like epilepsy?
