HDL, I hear you.
Christmas to me although not overtly stressful, just doesn't have the same something it did when I was younger. That seems logical I guess but what was once a time of great anticipation and excitement has become almost a burden to deal with.
This changed for me the year my mom died, and also the same year my grandfathers had a stroke Christmas Eve. So a few negative associations.
I decided this year is the last I will feel this way.
My wife and I are taking up a transcending type of meditation. Basically TM without the $1500 price tag, and without the wacky mysticism.
It is an inexpensive ($25) self learn course called Natural Stress Relief.
It can be ordered online, and learned over 3 days.
There is plenty of information on it, and can be reviewed and ordered at....http://www.natural-stress-relief.com/
Given the studies done about the positive effects on sufferers of PTSD, and the simplistity of it, it is worth a try, for us.
For what it's worth, I offer this to you and hope you can find some joy your time together.
