On my own and quite happy. DH's 83 yo widowed mother lives an hour train journey away and he doesn't drive, and she would be alone otherwise. I am working Boxing Day, so have to stay in London.
Don't be down about being on your own OP, it's only a date.
The media, shops, adverts, like us all to believe that there is something wrong if we are not surrounded by a couple of dozen people on Christmas Day, exchanging gifts worth hundreds of pounds and eating ourselves into a stupor.
They encourage people to gather in groups, spend beyond their means, and magnify the distance between the haves and have- nots. It must be horrible to have these 'perfect' scenarios constantly pushed in your face if you are alone, grieving, suffering the loss of your children, parents, jobs, homes.
It is a hugely cynical marketing and spending frenzy.
If people want to celebrate like that, then good for them. There is not a wrong or right way to do things, but don't let the marketing men convince you that there is.
