Hi debbyx,
Sorry to hear you are feeling this way. If it helps I too have found the Christmas madness increasingly more difficult to manage over the past few years, so I started to develop some techniques to deal with it better whilst still enjoying the magic of Christmas.
I'm generally quite organised and buy presents over the year when I see things I think people would like, rather than just for the sake of it, or in the sales. It spreads the cost and also means there is no pressure to go Christmas shopping at the busiest time of the year as I have developed a disliking of crowds.
My main issue is the number of requests to "catch up" with people who haven't been that bothered for the past 11 months. It feels like a tick list. So I make sure I schedule things in over the month, spaced-out, with some of them, then tell the others I'd prefer to leave it til the new year when it's not so busy. Unsurprisingly most people seem happy with the "in the new year" suggestion. My social battery can't take endless back-to-back events.
I can no longer tolerate the noise and crowding in cafes and restaurants, generally, where you end up shouting just to have a conversation, let alone in December when everyone is "catching up". It is sensory-overload madness.
I've also learnt to keep my diary as free as possible in the last few days running up to Christmas Day as we generally get a few last-minute, dis-organised drops-ins who I really do love to see, but it then means I don't feel rushed or compromise my own plans.
Some of this stuff maybe too late this year or not possible for you but just some ideas. I suppose I try to remain as much in control of Christmas as possible, with the expectation that there will be a few curve balls that I have to deal with when they arise.
I hope you manage to have a peaceful Christmas and look after yourself. X
