Well, I've been cancelling xmas for a few years now even before I thought I was Aspie.
I was Done with Christmas Cards a long time ago ( ) except to my family and have a good reason to be in my own home away from the madness as the parrots need feeding of course.
I gave up displaying any cards I got and don't decorate at all now. I really like this arrangement. I go into work in the holiday to keep a mental hand in. It's all about keeping a normality through two weeks of holiday celebrations for most people. (getting into the spirit of it for days on end is like a rabbit hole and difficult to get out of)
I feel blessed and thankful
It will be interesting post dx for this year, as I'm starting to let my mask drop and be the person I really am. I will be testing the waters. No more expectations
