You tell her she's beautiful, she'll tell you "No, I'm not." You tell her she isn't fat, she'll say "Do you see this?" You compliment her on her looks, she'll tell you "There's girls out there that who look better than me." Do you know why she doesn't take any of your compliments? It isn't because she likes hearing it, or wants you to keep repeating it, but because she truly feels like she doesn't deserve the compliments being given to her. She knows her own flaws better than anyone else, and they stand out to her more than anybody else. So when she looks at herself, she doesn't see what other people see.
