Jill: I don't think there is anything you can do or say at the moment since you really did nothing wrong. And in time she will realize that too. I think you should just be the same Mom you've always been - someone she can trust. Someone who loves, respects, supports and is always there for her. Time will fix this if you don't apologize for something you didn't do.
Hang in there. This too shall pass. Your D knows the truth. But sometimes the truth hurts.
