I look upon Depression like that huge roach in the movie "Men in Black" because, to me, giving it a face helps me to fight it. I'm on the Depression Board and although you are talking to your friend, I hope you're going to try to get some other help for your depression. Things don't have to remain the way they are.
Let me make the suggestion of finding a local depression support group. They are usually supported by the mental health societies in the area and they provide lots of resources, but also members can suggest what has has helped them.
Good luck and many hugs.
