I agree w/DnJ...sounds like your wife wasn't playing very nice last evening w/her mother. Generally, while in the throes of MLC some actually do not get along w/their parents and/or siblings. Why? Because family is concerned and tries to reason w/them and point out the error of their ways. MLCers don't like that.
As for asking friends, etc. to check on your wife periodically...your wife is just fine. Looking bad is all part of the journey for them. They tend to get sick quite often, they don't eat properly, nor do they get a full night's sleep. Why? Depression at its finest and the demons at night like to play handball in their heads when all is quiet w/no distractions.
Keep the focus on you and your children. Your wife is doing all of the typical things that a crisis person does.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
