Look. You've been working diligently on your project. And as far as I'm concerned, you're a writer. In fact, if your "friend" can go around putting down other people's work, SHE is not a true writer, not you. Maybe being the star in the writing class has gone to her head. But I bet she'll be quick to apologize when your work gains a cult following and gets various movie and video game adaptations and late night specials on primetime TV.
