I used to work retail far from where I grew up, and everyone I knew would go home for the holidays but I would have to work. It was tough sometimes but also it’s just another day, I “took time off” from my home chores to go do what I want once I was off work or if I wasn’t feeling up to it, just stay in with a frozen pizza and watch horror movies.
I’m not sure if that helps, but even though it did rob some of the remaining childhood magic for me, changing the view of holidays to be more mundane helped me feel less bad about my situation and enjoy the fact that I had some time to do whatever I wanted.
