I'll be your tumor

I feel like such a bother. Am I the tumor in your life? You know I have nowhere to go. No matter how hard you try to beat your tumor, bend me to your will...It will never go away. But you are different, you can choose to run and hide/ but you do not. Your face is illuminated by a loop of bouncing sass and bobbing ass, in your reflection I see darkness.Do you plan your revenge. Do you feed off me?
