Well, millions of people in America alone have mental conditions that go undiagnosed for years, or never. Just because it's not completely crippling her life in every way possible doesn't make it something to simply brush off. That's why so many people end up on the streets or in some psych ward. Show a little sympathy, eh?

I think I would try and take a little vacation like mentioned above, or even see a pyschiatrist if at all possible. Maybe not as like a weekly thing even, but just a few visits so you can get your head straight and seal that crack. : )

Best of luck.
