Ever have that feeling you are in a good mood, and then you just feel blue all of a sudden with no reason or cause?
You are in a funk, and there is not reason to feel this way and it gets your mind wandering about a lot of different things, and even the normal stuff that puts you in a good mood doesn't seem to work.
Then as suddenly as it came on it is gone and your left thinking what the funk was that?
Could last seconds, minutes hours or longer, but you never really know why, and for awhile you dwell on it then even that mystery is gone.
Lost.
