Sounds like shes been torn between two poles, diving into beyond to cope into the middle. It is tough to see and understand closest one in that situation. Takes more patience than love. Does love pay off? Do they love us back? Are they worth it? Is love worth it? Too many questions to tell what I think about this, its more a feelings that takes too many words to describe.

In short, rationally, I think she is hopeless bipolar. Emotionally, I feel her and also feel that I would enjoy with her on good days more than I would suffer on the bad ones.
