It's the unwelcome visitor that chooses to visit when you are trying so desperately to deal with the other issues that life has dealt you. (and doing a pretty good job of it). It can sneak into your head on a day when you think you are dealing with life just fine...and knock you flat on your *****. Turn you into a totally different person that you were yesterday...a person that just wants to pull the blankets over her head and be left alone....a person that just wants to hide from the world...
