In seriousness, I get a little bit of depression with my MS attacks to start off with, it is like this at first, a little tear here and there for apparently no reason and then I can only describe it as a bit of a cloud descending, outward signs are minimal but inside you just feel like curling up into a little ball and making it all go away.. Just keep an eye on it, make sure there are people around who know you and can advise you if you're getting moody or distant. If it goes no further just put it down to hormones today...
