Christmas can certainly be a very sad and lonely time for some people.
I really like Aorinsis suggestions and examples of how to make Christmas new, different and meaningful for what your life is at present.
One year I assisted with a community Christmas lunch. I really enjoyed being a part of that. Due to family expectations I have not done that again since, but remember what it was like being with people who had wanted to be with others on Christmas Day.
Writing here how you are feeling can certainly help. If your children are old enough, encourage them to talk about how they are feeling around Christmas and what their expectations are.
Christmas Eve and Christmas day, I like to light a candle for those who are not able to be with us for one reason or another.
I try to invite other people around for Christmas when possible, friends I know who don't have family close by.
One year we had a $5.00 mystery gift. All the presents were put in a box and you pulled one out. After the gifts were open, there was a lot of bartering and laughter happening. It was fun.
Our family have told us what we are doing this year, so guess we will follow those plans and make the most of Christmas along the way.
Cheers all from Dools
