This is just an aside for those who dread Christmas alone:
If you have the means, from now until 1 December, start ordering yourself some treats. Need not be costly; I focus on used books via Amazon, home spa or beauty products, craft supplies, candles, incense, DVDs, pet toys if you have a pet, puzzles, tech gadgets like a bluetooth speaker, maybe a pashmina, whatever does it for you.
When they arrive just put them away unopened. In a box under the bed, closet, garage, etc. Resist the urge to look.
Even if they aren't wrapped in pretty paper, by the time you open them on December 25 there will be at least a small element of surprise (if you are as forgetful as I am) and you'll have some treats to eke out over the day. This gambit has really saved the day on the Christmases I have spent alone since most of my family members died.
I really prefer a home alone Christmas with food treats, my few self-ordered present, Christmas/classic films or carols, candles and other comforts to being a fifth wheel perched on the edge of someone else's sofa.
Same for New Year's Eve: have a plan that involves comforts, treats and pampering.
