You might be unpacking your Christmas decorations from last year, watching a happy family on a TV commercial, or talking to a friend who is planning a dinner and this wave of grief washes over you unexpectedly. No one has died, you think to yourself so why am I so sad? What if you were recently divorced and your family is now very different from years past ? What if you don’t see your kids on Christmas Day or they are only coming over after 2 pm? What if you are going to miss the morning present opening?
