The first Xmas after I JFO was very hard. We had moved over 1000 miles from family, so it was a first Xmas without them around. But it proved to be a blessing, we started a few new traditions to take the edge off.
The next Xmas was after a really bad period, the short version is false R due to trickle truth of epic proportions handled very badly. But again, what saved it for me was establishing a few more new traditions. We went out to a tree farm and got a live tree for the first time on Black Friday, saw Santa, came home and decorated the tree with only handmade decorations. The kids and I did several mission projects with our church, and they performed in the Xmas pageant for the first time. It literally saved the season for us.
I know your kids are older, maybe not all live at home, etc but I suggest starting a new tradition or two with the kids. Go see a holiday play or performance, go do a charity thing together, go ice skating, whatever would appeal to them. Whether WH is involved isn't really necessary, the idea is to do something new and different to celebrate the season. When it is a new thing, there isn't anything to compare it to with the family as a whole before.
My other suggestion is do something for just you. Go get a massage, or go to a craft show, or whatever is YOUR interest on your own, or with a friend if you prefer. It is time to do something for yourself to renew your spirit. This will help in been in the right frame of mind when you start your new traditions with the kids.
