The one I'm working on right now. It's since been re-written and is a lot different now, cause when I found it and read it years later I still liked a lot of the themes and characters, it just... needed to be a LOT less... emo...
Originally I wrote No Future when was I was 14 and was heavily depressed, due to family life via. relatives fighting with mental disabilities (that were often dangerous to other family members), living in the closet about my sexuality, being treated like crap in school by the teachers, being treated like crap by my friends cause I didn't have money and couldn't afford to go places to hang out with them or buy the newest thing, feeling like I didn't have a identity and wasn't allowed to have one because I was a mixed kid, pets dying, and the general feeling like I was going to get no where in life because everyone said I was stupid and I honestly believed that I could never be smart and I would probably end up with one of the violent mental disabilities that seemed to be prominent on my mom's side of the family. (just to name a few things going on at that time) So yeah, take all that frustration, depression and anger and just mash it into a story.
The story was dark in a depressing way, with no good outlooks in life, nothing getting better for the main character, and Sin (that was the main characters name back then, don'tjudgemeIwas14) realizing as he went on that nothing he did mattered cause things were just going to get worse and he would never live out to do what he wanted to do, people around him would die, or get hurt because of him, while he himself though wanting to be important would never truly be important. The story never got better, it couldn't, cause at that moment in my life I didn't know the concept of 'things getting better' it was just not something I experienced. Things just continued to get worse and worse with the main character realizing how useless, helpless and worthless his existence is in the grand scheme of things. The story didn't have an ending, because I stopped working on it when I realized it wasn't going anywhere and I didn't know how to end it. I couldn't fix anything.
I think if I had finished writing it, it probably would have ended in the main character committing suicide, and to me at the time it would not have been a sad ending. It would have been a happy one.
