Shannon

"Life's been hard for me. For a while, actually. I'm broken. Whatever normal people have that lets them shrug off the cynicism and the madness, I don't. I've looked for an answer, but it's not out there. Or I'm too tired to keep looking, I don't know. Soon it won't matter. Please remember me as the little girl who snuck into your room after nightmares--not the disgusting mess I am now. Goodbye.
