reconciliation after divorce?

[any chance?]

I really feel like I am talking to myself here. I am concerned about the health and well-being of my W, who is in a major depressive tailspin. Is this common? How should it be handled? She is isolating herself from the world. What to do? I reach out to those on this site who have experience and seek advice. Please provide some insight - I would really, really appreciate a response. Thank you.
