Whether you celebrate Kwanzaa, or Christmas, or Hanukkah, or Festivus, or the Winter Solstice, or some appellation of your own, Happy Holidays to Everyone!
In my experience this is often the most horrible time of the year. A real slow motion emotional apocalypse, but over the years I've mellowed in my responses and am learning to accept what comes and always offer in return, as much as I can, something warm and friendly.
Good friends make all the difference. Surround yourself with them if you can, or keep them in mind if you can't. If being with Family is difficult, search for compassion for them as well as yourself.
And where ever you can "Reach out and touch someone."
A little kindess goes a long way.
