DC18 and I are a lot like that, both starting from a very young age. Delving into philosophy and theology helped once I was a little bit older (teen years and into college) and better equipped to deal with the issue and to make sense of the world around me.
Also, some movies and my intensity/sensitivity did not go together well as a younger person, and, although it rarely happens now that I'm an adult, that movie unhinged me for a couple of days as well...
