What a weird thing smoking is and I can't stop it. I feel cosy, have a sense of well-being when I'm smoking, poisoning myself, killing myself slowly. Not so slowly maybe. I have all kinds of pains I don't want to know about and I know that's what they're from. But when I don't smoke I scarcely feel as if I'm living. I don't feel as if I'm living unless I'm killing myself.
