Another (US, yes, other cultures feel free to substitute your own here) Thanksgiving. I don’t really enjoy turkey, I have food issues anyway, feasting is very conflicted.
Then, there is the enforced extended family togetherness, the clueless rightwing folks carrying on vs the suffering vegans. Everyone expected to be happy. This is almost beyond cliché, but it’s real, happens every year.
So here’s the question, would be happier to skip the “celebration”? I put celebration in quotes because it sounds to me as if it is far from a celebration for you.
If you would be happier skipping, if your mental health would improve due to avoiding all you mention, then your responsibility to yourself is to make your excuses and not attend.
I started skipping the big “celebration” and now just make it at home. It turns out I actually do like Thanksgiving food if it’s prepared by someone who knows how to cook and actually served hot. Previously, I was used to dishes made by people who had no business making them and food served lukewarm because the amount of people that you had to get together on the same page to finally fucking eat.
