One of my favorite books is Bridge to Terabithia. I've watched Beaches more times than is probably healthy. When writing for my first fandom, I managed to write at least one story where one of each character died.
I like angst.
For a long time, I just thought it was a particular spot that appealed to me, and I rolled with it. I joined fandom while my father was in hospice care, so my slight obsession with death made sense.
The older I get, the more sense my attraction to these types of stories makes. It's not necessarily the angst that attracts me, it's the emotional response it gives me.
(Side note: I also love cracky stories. The more ridiculous,the better for me. So I suppose I like extremes.)
I'm an introvert with social anxiety and depression. I have a hard time expressing feelings unless they are super intense. When I get angry, I'm the Hulk. When I'm frustrated, I cry.
When I look for fiction, I'm immediately attracted to something that is going to give me catharsis.
I don't need these things to be alive, I just need them to actually live.
