[OMFG!You'reActuallySmart!]

Many people have a fascination with death as morbid as it sounds. When writing about it, you were excited by a story, nothing bad to me. The feeling may be addictive because you felt so excited and the rushing adrenaline felt wonderful, so you want it back. There are many authors who are excited to write about murders or similar crimes yet they are fine. It wouldn't be fine if say, you wrote about a story then you acted out the killing on someone.

Your adrenaline rush is to something many may disapprove of but it doesn't mean you have a mental illness. Others may say otherwise simply because it's a 15-year old girl writing about murder stories, which isn't something that occurs often so people say something is wrong with you. I disagree.

If it ever comes to acting out the stories or getting sexual releases from any torture or killing you write, depending on what it is you wrote, that wouldn't be good.

I'm basing my view on the fact I have many books about murder cases that do go into quite a bit of detail, serial killers, books dedicated to only one serial killer, etc... . Those authors are mentally healthy, some work in the field as forensic psychologists or police.
