Seasonal Affective Disorder
Some people get depressed in the winter. Along about October or November, they start to feel lethargic. They want to sleep a lot. They crave carbs and gain weight. They may lose interest in their normal activities, not want to see people, feel hopeless, think about death. The deeper the winter, the sadder they feel. In April, they start to feel better, regain their energy, and even feel giddy by the time May comes round. It happens almost every year.
This is a specific kind of Major Depressive Disorder called SAD, Seasonal Affective Disorder. It is no fun.
