When I first read the title of the post, I chuckled...'cos it was unexpected, I guess. But then...well, I hate showers, too, when I'm depressed. I don't like leaving the warm bed (and often, one of my kitties snuggled up with me). I don't like getting wet, being cold after the shower, trying to do something with my hair...all of it, ugh!
But I have to admit...if I can get myself to take one and get dressed, well, I usually do feel a bit better for a while.
