Already Dead

People say I'm dying because of my pale appearence. But the truth is that I'm already dead. Emotions make the person live, as people say. But I don't have feelings. My closest friends refused to acknowledge me. My mentors don't even know I exist. People see me as a monster. They put me down and try to break me. But they don't know that I put my life on the line just to save their stupid lives EVERY SINGLE DAY!!!! I take on majority of the missions and patrol every night. While their fawning over their "heroes", I'm the one who is in the back making sure that everything is safe. Don't try to kill me because I'm already dead.
