Seasonal Affective Disorder

The Mayo Clinic defines Seasonal Affective Disorder as:

"A type of depression that's related to changes in seasons — SAD begins and ends at about the same times every year. If you're like most people with SAD, your symptoms start in the fall and continue into the winter months, sapping your energy and making you feel moody. Less often, SAD causes depression in the spring or early summer."

I think that as far as I am concerned "depression" is somewhat exaggerated, but several consecutive weeks of terrible weather makes me feel "down in the dumps."  It is either bitterly cold, snowy, or both.  I just hate having to stay in the apartment.  I miss taking long walks, but the only thing I can do is wait for spring.
