Get a new teacherWalter Ramsey
Actually, I don't entirely agree with the last two posts. Sure, find somebody who can help you with this piece specifically, but it doesn't mean you should just dump your current teacher altogether. I have experienced teachers referring students to other students for help on particular repertoire. Well, if the students being referred to for help with specific repertoire were initially taught by the teacher, why is the teacher referring students to other students for help ? Each individual will have something unique to offer and, if somebody is more familiar with a particular composer or style (or piece), perhaps it's a good choice to study that piece with that person. Anyway, what can't she help you with, exactly ? I guess she can't play it for you anyway.
