Have a mother/daughter day with her. Go shopping, get her to open up and talk to you about what is bothering her. Is it school? Is it kids bullying her? Does she not feel pretty? At that age, most girls start to focus on relationships, crushes, etc. which is also connected to how they look, how many friends they have, their popularity, etc. Perhaps a makeover might help her - you can give her a manicure/pedicure at home, try a new hairstyle, try new clothes...but remind her that what really matters is that she has so much to give but is still "in training" before she can really see her purpose in life. Hug her often, ask her for advice on a few things at home to show how much you value her thoughts, give her small projects and praise her, let her catch you bragging about her to a "friend" on the phone.
