Carving the turkey with friends and shopping for a gift for someone special is a part of life during the holidays. Drowning your troubles in egg nog and pigging out on holiday candy is not the solution. Before you get defensive about that statement, I suggest that you take a closer look at the real issue that brings on this feeling. It is not in your best interest to allow what you think to color how you feel. If you are already feeling down, alcohol depletes the brain of serotonin, a chemical it needs to maintain normal mood.
Party drugs can only create additonal relationship stress.
If you are lonely, show up where people are. Ask friends to help you donate toys or clothing to various charities. Volunteer to help prepare and serve food at at local soup kitchen. Exercise and keep those endorphins pumping, especially if you have a tendency to avoid your feelings of loneliness by sleeping too much. Often the moods of the seasons are affected by shorter days and longer nights during November and December.
