Get her to see a doctor. I'm serious. Drive her to yours if you have to. Find one that can make the diagnosis of depression (if that's what it is) -- some doctors don't feel confident enough to diagnose behavioral illness. And make sure it's someone who has worked with antidepressant therapy and knows what works and what doesn't and on whom.

Untreated depression is the #1 cause of suicide in the US&A (and probably similarly high elsewhere). Treatment for clinical depression is safe and effective these days.

I know, I are one.
