-tiredness,
-fatigue,
-depression,
-crying spells,
-irritability,
-trouble concentrating,
-body aches,
-loss of sex drive,
-poor sleep,

-overeating, especially of carbohydrates, with associated weight gain.
In severe instances, seasonal affective disorder can be associated with thoughts of suicide.

My own remedy: try to get as much sun as possible. Go outside. Sit by the window. When it’s really cold I sit by my window on the floor or in my rocking chair and let the sun touch my face as I drink tea and read a book. Even as I work on the computer I try to get some sun as in the winter there aint much of it and its not so so strong but it does warm my soul. Sometimes I do the yoga Sun Salutation to the sun and in the sun near the window, and that is nice.
