I recently had an issue where I was driving I went to the ER and they could not answer my problem. My sister got me to pull over I was repeating I M Fine over and over and she put car in park and I was still acting like I was driving. she also called my husband they said my eye were extremely wide and dilated and they talked to me and asked me my name and I would say I m Fine. They got me to eat a cookie thinking my blood sugar dropped. They got me out of the truck and I staggered around like I was drunk laughing and then they got me in to my husbands car which I then started to cry. At first he thought he would take me home and that is what he did and went to take me out of the car and I collapsed and they put me back in the car and by that time I was coming around and asking how I got in my husbands vehicle and how I got a cookie and where we were going and why and what happened because I could not remember.
