Yes...when the depression is gone, the enthusiasm returned for me. When the depression is deep, like it is for me now, there is not any joy that I can find in anything. But a year ago, I was "up" for everyday. For me, it is, and remains to be, an employment issue. Make sure you are doing what you want to do with your life. If you follow someone else's idea for you (as I did because it was supposed to make me financially secure and it has not) you'll end up depressed.
