I exclusively read nonfiction until I had a traumatic event happen to me. After that, I read fiction nonstop for several years. Fiction was the only thing that could help me process it. (Note: not escape the trauma, but help me process it. Nonfiction was too clean, black-and-white, etc. Too simple. Fiction presented a world of uncertainty and doubt that I could live through and thus reflect upon the traumas I had undergone.)
