This is an article from my files from when I wrote for the Somerset Times Weekly. (2008-2012) I feel it is still relevant.
Emotions can either rise because of the
Christmas season or close in on a person who feels unloved or put upon by
others. Studies show that four to six percent of Americans suffer post-Christmas
depression. Many of these people are isolated from family and friends, not
necessarily by social distress but by choice. Many sufferers begin getting
depressed before the holiday and slowly begin the isolation process,
overwhelmed by the stress of shopping and resentment of pressure from what to
give to who gets what. This makes the person close in on him or herself and
seek to be alone, wanting the noise, and bustle to be over so their lives can
get back to normal routine. Some people feel pressured by the Christmas Carols
played extensively in stores and public PA systems. The songs meant for joy and
festive ambiance heightening the emotional stress. These feelings can become
dangerously extreme by the New Year.
People who have lost loved ones during the year
feel the loss more because they don’t have that person in their lives to enjoy
the gift exchange, food, or parties. The void is sometimes impossible to fill
even through many years. Facing the New Year can be tough for those living with
such a loss.
