These days are almost always incredibly one-sided. Either you are totally unable to get past the gloom of the black sky, or you find something to make yourself happy. But the darkness can get to your head, and moving from a dark world to a building filled with fluorescent lights isn't gonna help that. You need some event, it can even be a tiny thing like someone smiling at you, but you need something to make you feel like the day is worth living after all. If you don't have the cheering up event occur within an hour or so, the day will be ruined, but hey, there's always tomorrow.
