I was in that place where your spouse is at a couple years ago. I don't have any advice, I am so sorry. It has to be hard for you, though. I know, for me looking back, I had to realize that there was something wrong...kinda 'snapped out of it?' I don't know. I am weird though. This probably didn't help whatsoever. I am sorry you are going through not only your depression, but dealing with trying to be supportive to her as well.

(hope a hug is ok)
