P.M.
It's gonna be okay, Kim. Everybody has had days like this, and all of us will probably have them again. Don't lose sleep; it will only make tomorrow harder. Your husband may have needed to be by himself to cry, for all you know – don't assume it's a reflection on you. Just be there for him tomorrow.
An airhead? Laugh – it's true, isn't it? So what? Don't carry today's "failures" with you, or they will only multiply. Pray or meditate if those are in your reach – they will truly help you get centered again. You don't want to start tomorrow off-balance.
Courage, and don't forget to breathe.
