If you woke up feeling a little down today, you're not alone. This was the Monday of the last full week in January, and that is generally considered the most depressing day of the year.
It makes sense when you think about it. Most of our holiday decorations are packed away, but the holiday bills are coming in. A lot of areas are coping with cold, damp, dreary weather, and for many people, the promises made on New Year's Day are already history.
So, if you feel depressed and don't know why, this is what's called "Blue Monday," according to psychologists at England's Cardiff University.
