Good for you for setting up an appointment to talk about it. I've never been depressed myself but do have people very close to me dealing with it. One thing I was surprised to learn about is the physical pain that can accompany it. A comic I found on Twitter wrote a pretty interesting blog post on what his life is like as somebody with depression. While it's quite a bit more intense than yours is at the moment, I think it's worth a read.
