It's the most wonderful time of the year, yet some people can't help but get down in the dumps around the holidays. It's ironic that although the season is supposed to be chock-full of cheer, it's often just the opposite. {relatedarticles}According to the National Mental Health Association, there are many causes of the holiday blues. They can include fatigue, financial concerns, family drama and much more. Many people set themselves up for emotional failure by expecting something out of a Norman Rockwell painting. Experts suggest that you lower your expectations for the holidays. Try not to take on too much. Figure out what you can reasonably do without completely overtaxing yourself. If it feels like too much, it usually is. Recruit a support system. Give tasks to loved ones who are willing to lend a helping hand. Don't try to be a martyr. The more you can take off your plate, the better. Always make some time for yourself. Squeeze in a nap. Sneak away for a pedicure.
