What's another word for "I-don't-know?"

Everyone's got a story, you're told over and over its worth a million things. A memory, a thought, a hope, a dream, a fright, a terror, it all comes together to form a mosh of a mismatched picture that dictates the existence you live. Kind of like a messed up version of fate. Can you change it? I sure as hell don't know. But I guess this is finally my time. Finally the time I'll just say whatever, spill it all out on paper. Cause this white sheet of nothing means more than anything. But how can nothing mean anything? Just wait and see, you won't have long to wait.
