"Then she described her own box she made for herself, and she told me that whenever she reads something inspirational she writes it down and puts it in the box."
Maybe you could write down all the ways it hurt you to get an empty box, put them inside and then share it?
You wrote " I'm hurting. It's empty." That might be a good start.
You could tell her it was a good lesson in "self-help" to let your feelings out.
She might not have a clue how much this hurt you. I bet if you brought it up next time you could work it out.
I really have no words of wisdom, especially right now because I really feel your pain. I would not only be hurt, but pissed off too.
