Is there a such thing as yearly depression?

[littlebitofluv]

Every year around the same time I get depressed, even before I had a traumatizing experience a couple of years ago. Usually between January and February. I know there is a depression that is seasonal, but the symptoms that were for the winter I'm getting in the early spring. I was just wondering if there is a reason for this, and why does it happen only this time of year? Is it because of my bad experience? Also is there is a special name?
