I need some serious help. Please help!!!?

I think you have every right to tell her how you feel, because you might have been too shocked the moment she dropped you to say it. It will help you to move on, or at least feel some relief that you let her know how much she hurt your feelings by doing what she did..and it really doesn't matter what happens after that, other than you will feel better that you let her know it, when you were in no condition to do it before..k?
