This is an absolutely great description. My biggest problem has always been that people are much more familiar with the black part of depression. My depression is almost 100% of the gray variety. So people are always confused because I don't seem especially sad, self-hatey, or unhappy. It's incredibly frustrating. I can't count the number of times I've said the words "I'm not sad, I'm depressed" with no one really understanding what I meant, and me not having the better words to express myself.
