I think the opposite might be true for some people. That is, depression causes stress. I think stress can mask depression. The first time I got depressed, I do remember initially (for the first few months) feeling blah, miserable, apathetic etc. After that (as I was falling behind in responsiabilities), the anxiety began to kick in, perhaps as an adaptive mechanism (i.e. if you can't find positive motivation to do the things you need to do, I'm going to use negative motivation i.e. anxiety, to get you to do the things you need to do). But it didn't start with anxiety or insomnia. Those symptoms came after the depression got more severe.
Some people only have the motivation to do things when they are under stress. For these people, its as if the brain circuts involved in taking pleasure in being proactive are not functioning well. As a result, a more reactive, coping strategy is used.
