I remember this stuff from my school days and my 12 year old is going through this right now as well. Girls can be so catty, so mean to each other. My daughter's ex-best-friend never even talks to her anymore. They used to be "BFF" (best friends forever). My daughter pours over her picture album, mourning for her lost friendship. These two girls were tight since they met in kindegarten and they "broke up" just this year. If I could do it over again, I would advise my daughter to have lots of friends rather than one best friend. I don't think she even knows how to make friends at this point. In fact, she stays home alone almost always now and my heart breaks for her.

My daughter went through this last year and has come out on the other side - but we had to take her to a therapist to get there. Like your daughter, mine couldn't get over her loss alone. However, within just a few sessions, my daughter was really back to her old self and able to move forward. Sometimes a professional can impact on a child in a way that a parent just can't.
