This season brought colder temperatures, steady snow, and real challenges across Delaware, Pennsylvania, and Maryland.

If this sounds familiar, you are not alone. You may be feeling the effects of Seasonal Affective Disorder (SAD), a well-documented seasonal mood change that typically starts in autumn or winter and naturally lifts in spring and summer.
