I so know what you mean. Just on Tuesday I was meeting with my therapist, sobbing and saying, "I'm not even sure anymore what would make me happy." Because I was so deep in the depression I couldn't see it. And now that I'm crawling back out again, it feels like there's hope again. But I think you're absolutely right that it pays to think about this sort of thing when you're not as depressed so you have something you can hold to your heart when you are. Sometimes when I'm depressed, it's even hard to get myself to do things that genuinely would make me happy, because when I'm depressed they don't sound appealing anymore.
