@Mame,
would you like to buy some Mary Kay Mame?
In my 30's, I was taking some classes at a satellite location of a college. This one class ended late, around 10:30pm. To get from the school to the interstate you had to drive what felt like endless miles (probably 10) on a dark, and at that time of night, mostly deserted highway.
One night I was soooo tired, it had been a really long day, and I was still half and hour from home when I reached the interstate. I made a left to get on the North bound entrance ramp, only I neglected to drive over the interstate overpass, and made a left onto the exit ramp of the South bound highway.
I only drove a few yards, someone getting off the exit started flashing their lights, and slowed way down and to the side. He slowed down more when he came abreast to my car, I guess to see if I was drunk or something. I called out to him how sorry I was, it was a mistake, etc. and he stayed in position while I backed up and got on the right way.
I was really shaky after that, and was afraid I would somehow fall asleep, although there was little chance of that.
For the rest of the semester, I'd find myself slapping myself, playing really loud music, talking to myself, anything to make sure I stayed awake. It wasn't so much the thought of killing myself, but the thought of taking others along with me.
