Feeling More than just “the winter blues?” You could be experiencing Seasonal Affective Disorder (SAD).
Seasonal Affective Disorder (SAD) is a type of depression that's related to changes in seasons. SAD begins and ends at about the same time every year. It predominantly arrives at the start of fall and continues into the winter months, often making you feel moody and lethargic. As we enter the season of shorter, darker days, some people may develop seasonal depression.
