By the time I was in High School, I was reading lots of Fantasy and Sci-Fi Novels and listening to classical Music almost exclusively. Between that and my utter social ineptitude and anxieties, I was all but invisible.
So when I wasn't thinking about imaginary places like Middle Earth or Dune, I was nearly suicidal with loneliness.
Aside from Band, Photography, and German class, it was a pretty hellish time for me.
