Do You Have Depression?

Over the last few weeks in Oakland, it's been hella cold, rainy and rather dark. Plus, have you noticed how quickly night falls?

I've had a couple of friends tell me that it's this time of year when they feel a little sad. They don't know if it's depression, but that feeling tends to linger.

Yahoo Health has a little quiz to take to see if you're in the throes of depression.
