Broadening the definition of "you" to include your whole body doesn't make you an "uncaused cause" because you are at the mercy of everything in the universe that led up to you and that influences you now.
I'm assuming a universe that has no supernatural causes, but it needn't be deterministic. Even if you interpret quantum unpredictability as true randomness inherent in the physics of the universe, randomness by definition can't be controlled. Various physicists have suggested "hidden variables" behind the unpredictability, opening a window for free will, but as of yet there's no evidence for them.
