You expressed the emotions VERY well. I remember contemplating life and death while I was trying to go to sleep the night before I drove my laps. It's a very beautiful but eerie place isn't it? I feel lucky That I got to do it before I turned 30. Here's one of my laps in the VERY wet from 2 years ago in an RSR car. You'll see the track entrance/exit was closed when I finished my lap because 3 cars had hit barriers behind me... I definitely recommend driving it yourself at least once, but damn is it scary!
