Hmmmmm. I remember my mother acting like that (a very long time ago) and my wife acting like that over the past forty years. My mother was never diagnosed with anything and of course took no meds. My wife was diagnosed as depressed, and she does take meds, but those blow-ups still happened and still happen. And I, who am DEFINITELY diagnosed and medicated, sometime do the same thing. In all three cases the reaction of the spouse has been the same: a shrug, continuing doing what they're doing, and then the next morning everybody going forward as if nothing had ever happened. Unless you've got morning-after problems, why not just ignore it?
