Once DS was in his teens, Christmas just seemed too much of a commercial industry that caused me stress and angst. It remained like that for several years. But I found a place where a few hours a week makes a world of difference.
As I and others have shared here, volunteering can bring a special joy to your life. This is particularly true at Christmas time. We had our children's Christmas party on Friday. About 200 kids and thousands of toys, big and small. Today, Christmas lunch and then free turkeys and care packages to take home (and small gift baskets for both young and young at heart).
The sheer joy and happiness we observe, and the profound gratefulness of our guests is heartwarming beyond measure. It's hard for us to thank the thousands in our community that make us successful, but we do try.
So for me, it's the local soup kitchen. DW still does an occasional mission trip. I've read blogs here of folks who do disaster deployments.
Whatever your skill or vocation, there is a charity nearby that needs you. And you'll make new friends with like minded thoughts and goals. Consider going with a friend or SO.
Anyway, if there's a hole in your heart or soul, volunteering might do wonders. It certainly did for me.
OP, I really hope you find a way to turn the blues away. Christmas best wishes that it passes swiftly.
