My advice, please get her some help. I know that some people just need somebody to talk with & know that they care, which you do. Suggest taking a walk with her, doing something that you know will take her mind off things & try to have some fun with her. Just a suggestion, but sometimes it works. Might try watching a funny movie or just doing something silly, like running around the yard yelling & having fun. Or you might suggest that she see somebody that can help her, like a therapist, again, just more suggestions.
One of the best things that you're doing, is keeping around her & listening to her, that will help her out more than you know.
We're here, just believe me when I say that!
