to koi-boi:; She obviously suffers from an identity disorder and needs your help to overcome it, I would not try to confront her in a stern tone but try to explain to her she has no reason to think this way and she is the most beautiful person you have laid eyes on. Ask why she goes in public if she is so ugly, or why she lets you see her in person. Try to to convince her with logic and love that she is not ugly under any circumstance. One more thing you could do is to tell her even if the world sees her as ugly that she will always be beautiful in your eyes and you love seeing even half of her face.
