Truthfully, depression affects a huge part of the American population. In my work with teens, I have found that depression affects teens in a different way than it does adults. In the years that I have been practicing, I notice that teens often present themselves as angry and rageful.
Anger just seems easier to express.
As we get to be adults, our vocabulary continues to develop and eventually, adults are able to label the other feelings. My experience has been that teens just feel it. Please do not misunderstand me when I say that teens do not express it well. If they are grounded then they are upset, not at having to stay at home in their room, but more because they will miss out on what might be happening with friends, enemies etc. Anger is a quick exhalation of many of the feelings that I have already listed.
