Nietzsche's Eyes Lyrics

Cover art for Nietzsche's Eyes lyrics by Paula Cole

Someone help me out here: I love the lines "Now that I step back to see, I haven't been me" and "I take on the water till the dam threatens to break" Is it about a girl in a relationship where she has given her all to a guy who isn't giving back in return...and she keeps on taking so much shit from him and he consumes her and she loses herself in the madness?
