Something between friends

My best friend's b/f dumped her.. I guess because her Aunt keeps fiddling with thier lives together. Well, this just happened today. She called me today and told me that I was the ONLY one that understands how deeply she felt about him and the real her. She said that Nathanial, her b/f, was her world and that world came crashing down after they broke up. She doesn't even want to live anymore she tells me once...I hope jokingly. :/ She was broken hearted once before, by her..uhmm..2nd ex-b/f and he didn't even love her she came to find out sometime after they broke it off. It was for the same reason..sort of. Well, tomorrow I'm gonna talk to her but I don't know what to say. I want to be able to help her but i don't know if I can, I didn't go through what she did. I just...don't know. I can say that I'll be there for her whenever and for whatever she needs me and that I love her and the best friend I could ask for. I'm kinda scared for her.. I just..don't know what to say or do. Can anyone help me with this?

Please, can someone give me some sort of idea...or something? ..Please.

Tell her she should stop using men and her relationships with them to define who she is...that for the same reasons those ex's were attracted to her, so to will another man be and one day she'll the one that was meant for her...
