This has got to be the hardest time of the year. We remember people who are gone and, frankly, cry. A friend of mine once told me that it's all right to cry, "tears are like rain and help us grow." He was right.
Then everything gets harder when you go shopping. You can't blame people for shopping online. Too many people. Too short tempers. Too much stress. Too many expectation.
There's also a biological reason some people feel sad during this time of the year. S.A.D. is Seasonal Affective Disorder. Here's the website for what the Mayo Clinic says about it. http://www.mayoclinic.com/health/seasonal-affective-disorder/DS00195
Personally, and I can only say the following works for me--I try to be busy, eat healthy, and get enough rest. I kickbox, which helps me on many levels. While doing my kickboxing, I tend to zone out and my mind experiences peace.
Going to worship service and lunching with friends brings me past the peace into joy. So does staying warm with family and curling up with my laptop.
May everyone have a happy holiday experience regardless of what you celebrate. Look past the shopping lines and gruff voices and hear the music of life. It's there. It's you.
