White Iris just gave wonderful advice. You do have to stay healthy and sane yourself if you want to be able to be there for her. Your love is wonderful and it will be her rock. Even if she can't tell you how much that rock means to her, it will be what allows her to heal. Someone who has been hurt so badly by another human will act like a person in a life raft on the sea. They are in shock and think that the raft is also going to sink before they are CERTAIN they are on solid ground. That certainty is something that can only come with time. Until then, just hold true and she will continue to be thankful that the raft is there as she heals.
