Perhaps there is some overthinking by some, perhaps some become overwhelmed by what the feel they ought to be doing rather than doing what they want to do.
The pressure can be overwhelming if we allow it to be so.
The tv adverts and magazines don’t help by showing overladen tables, expensive “must have” gifts for everyone and their mother, perfect decorations, etc, etc, which can, if you allow it, make you feel inferior or failing if you don’t match up to this make believe “reality”.
It’s hard, I think, to step back from these false expectations, but really one has to try to preserve one’s sanity, and try to recall what Christmas is really about, not what commercialism would like us to believe it’s about. It’s not easy to step off that treadmill, though.
