By keeping her trust you are not helping her. If your intention is to help her then you must go to a trust adult for help. It is just possible that she has come to you and confided in you because she realizes that you are smart enough to do what she herself is not able to do. Asking you to keep her trust may be just her way of allowing herself to tell you what she had to tell you.
I think at the very least you should discuss this with your parents and let them help you with decide how best to help your friend. If your friend is not in life threatening imminent danger your parents will be the ones who will best help keep the trust your friend has placed in you.
