I know this feeling all too well. For me, it was the death of my marriage. We lost the cheer for the season. I gave away the tree. I used to just leave the string of lights outside the door and plug it to a timer, but this year that piece of shit isn't working either. So the lights that don't work hang outside my front door. It's too cold to bring them down. They've been there for a few years now so who cares how ugly they look.
I hope to bring back some cheer into my life, but it is just not happening now with disgruntled teenagers who are testing my limits.
Hope you get your hot meal this season. I've given up on that and just make it for myself in the name of self-care.
