Two halfs

To ever person there is a dark and a light. The more people think the different their personalities become. I don't have a light side only a dark, and the more my dark shows the more I want to kill. I don't want to kill but the fake smile I have is something that makes this happen. My dark side makes me insane and their is more to me then you think.
You see I have a crush but I can't talk to him without thinking about killing someone. So he will never know how much I love him and how much that I would like for him to be mine. My insane side gives me suicide thoughts, murder thoughts, etc. So my point about this whole think is that some people don't always have two personalities.
