My daughter is 17, the last three years she has experienced instances where during the day, she is still functioning but at the same time somewhat in a blacked out state of consciousness. She has no recollection of what had just happened, but remains functioning. She drove 15 miles to work, and when she got there, she started crying because she had no recollection of how she had gotten there, like she had instant short term memory loss, she had no knowledge of traffic, signaling, driving, anything its like she snapped out of it when she realized she was sitting at the work in the parking lot. What on earth could this be?
