Doesn't anyone else think that's kind of strange? At least, to anyone who's studied depression?
It makes much more sense for depression to be worse in the morning. I'm familiar with this because that's more my tendency, and I know of other people who have also had rougher times in the morning. The simple reason is because it's a new day without any promise. At night, you know you can comfort yourself through sleep, and maybe wake up feeling different or renewed. In the morning, you're at the mercy of the day in front of you. Suddenly the morning's here and everything's expected of you. This overwhelms many people with depression, and is in fact the riskiest time for suicide--most suicides occur in the morning.
Statistically, or so I've heard, more people with endogenous or melancholic depression have it harder in the morning. And, conversely, those with reactive or atypical depression have it hardest at night.
So to answer the question, "Is it normal for depression"...well, it's less common among those with endogenous, extremely severe or melancholic depression--the people who would not be on this board, but rather in psychiatric hospitals, which would explain the board's overwhelming response toward nighttime. It's more common for reactive, mild to moderate, or atypical depression.
