Kirsten,
This was happening before Lily's arrival? I think I might have her rehecked. And, let some time happen. Have you tried communicating with her? Asking her to let you know what is troubling her? I have a book at home, and I am going to take a look at it..and see what it has to say. Also, have you followed Jen's trials with Jim and Sterling? Have you done that? I wish I could physically DO something for you and Luna.
