When I was younger my Aunt Maggie would randomly get really depressed and irritable. I never understood why, but my mom always told me to just ignore it. As I grew older I started to notice that these ‘episodes’ would only occur around certain months of the year, particularly in the winter. I then observed some more unusual characteristics: she quickly gained a lot of weight, most of her free time was spent sleeping, and she became less involved in our family affairs. When she did get involved it was only to start unnecessary and petty fights. I couldn’t comprehend why she was acting so distant towards her own family. It was a known fact that she hated the winter along with the snow so when I was thirteen-years-old she moved from Newtown, Pennsylvania to West Palm Beach, Florida. After a year or so she was back in shape and her attitude was nothing but friendly. She no longer slept her days away, and even though she lived twenty-four hours away she still remained really close to us. I now know that what my Aunt Maggie was suffering from was seasonal affective disorder, but in order for me to fully understand what she was going through I must first understand the disorder itself. It is for this reason that I will be looking at the symptoms and causes in particular that are related to this disorder.
