This question was posted a little while ago, but if it's still happening then I'll tell you my advice anyways.

Self esteem problems are always tricky, you're her best friend so you know her really well, the things that make her happy and the things that don't. Just remind her that she's not, help her through it and if she continues to mope about it get a little more serious and let her know you care about her and you're worrying about the situation. and take her to another of your friends and just get reminders from everyone that all of her friends care for her.
