This is one of many things I dislike about Christmas.
We're always under pressure to conform, to be what other people think you should be or want you to be (usually to get your money!) but Christmas is just like a relentless wave of you must have this and do that, which goes on for far too long nowadays.
And you can't ignore it - it's wall to wall, 7 days a week.
If you want to have fun, see the family, get and give gifts, be nice to people... do that whenever you can. Don't funnel it all into one tiny part of the year where expectations are piled so high they risk tumbling down.
I get that that isn't everyone's Xmas... but there's a sizeable amount and for some people, Christmas is just a hell with no off button
