An easy fix is "light therapy" and a discussion with your doctor regarding getting prescribed an antidepressant such as Prozac. A study that came out from the Mood and Anxiety Disorder program at the University of British Columbia and published in JAMA reported that the combination of an antidepressant along with "light therapy" revealed a higher rate of symptom remission than without the "light therapy" and 50-80% of the subjects tested had complete remission with the "light therapy" alone.
