Adult onset Epilepsy

I'm 34 yrs old and had my first seizure two months ago. I had a Gran Mal seizure in my kitchen and don't remember anything until paramedics were standing over me and I was covered in blood from hitting my chin on the tile floor. I'm not sure, but I think I was having seizures before this one.  There have been three times when I thought I must have fallen asleep in my car in a parking lot, but I'm starting to wonder if I was really having seizures.  I would like to know if anyone had experiences like this before their first known seizure? One time I dropped my son off at preschool and drove to the store and the next thing I know someone was knocking on my car window asking if I was ok.  My wife had called several times looking for me and I had no idea that several hours had passed and it was time to pick my son up from school again. There were two other similar instances.  I just thought I must be more tired than I realized.  People think I'm a drug addict because I have done this like three times and I have gotten in trouble at work. 

 I'm currently on accommodation due to driving restrictions following my seizure and was at work.  I got a formal letter of reprimand saying that I had been sleeping while work twice in one day.  I had no idea what they were talking about.  I don't remember falling asleep or waking up all day....I just remember feeling a confused in the morning and another time during the day, I was praying and someone firmly tapped me on the shoulder to ask if I was ok.  I told them that I was fine, just praying.  To me it seemed like it had been seconds, but apparently much more time had passed.  I found out that people took pictures and stuck fingers in my ear and I'm not sure what else they may have done.  Has anyone had any experiences like this?
