I met a monster

Do good. Be good. Don't do this. Don't do that, they told me. But he told me different. Do this, do that, you won't get caught, don't worry. But they tell me, what are you doing? Stop. This is wrong. But he then tells me don't listen to them. Your fine. Keep going. I tried to ignore him, but he wouldn't leave me alone. I tried to ignore them, but they wouldn't leave me alone. But now it's to late. I can't stop. I'm trying to ignore him. I'm trying to listen to them now. But I can't. He's become this horrid monster. I always hear how monsters hide under your bed. But this one didn't. He crept up in a substance that traveled to my head. He then devoured me slowly. Making me go insane. Drowning me into the abyss of hopelessness. Trying to fight this monster. But I'm addicted to him. There's nothing I can do. I'm trapped in his arms. Trapped in the thing that they call this monster. Crank.
