There are plenty of ways of avoiding the hype, shop on line to avoid the forced jollity, don't watch telly without a plan to enjoy the best of what suits you, read good books walk in the winter weather. I would also avoid the various 'appeals' for money and help, it is just another day and can be treated as such if you want to. Charity can be dealt with any day.
I wish all the Christians the joy of the day, I wish all the parents who are doing it for the kids, the very best of luck, it's not for me but I will be celebrating the mid winter, Yule.
If you are grieving it is hard, but an essential part of that process and nothing changes your pain but time.
We will be here on GN over the holidays so you will not be totally alone unless you want to be.
As from Christmas, the light will begin to return and spring will be on her way, if that's not a reason to celebrate I don't know what is. No hype needed for that no beliefs, no mince pies, just a time to remember how wonderful it all is.
