If your present way of doing Christmas is upsetting and exhausting you then the only way to change feeling that way is to change your Christmas routine
E.g if you host extended family have them eat at their own home and then meet up on Christmas Eve or boxing day to exchange gifts ...
Or if it's the cooking itself you could buy a pre cooked turkey ( I remember my mother used to do that,I think you collect it Christmas Eve or early morning crack of dawn Christmas day...she used to get hers from a local butchers shop, she swore it was a game changer in making it easier for her
If you don't want to cook at all, could you buy tickets to a local pub, restaurant, hotel etc and dine there for Christmas dinner (I know from my town prices vary by place so if you do decided to do it then shop around for your price budget....you could even get a jar and put a little in each week and call it the Christmas dinner fund and by Christmas use it to pay for dining out in Christmas day and any extra money use for buying your other Christmas food in
For gifts, if you buy their gifts from amazon you can click for them to giftwrap it and you can type personal message for the gift tag (total time saver, )
For your Christmas tree if they won't help put it up and decorate it, I think in argod and on Amazon there are trees that come with lights and decorations kind of fixed to them,
For Christmas cards, buy a box in the sales, write a few to family and friends, neighbours etc and then put them back in the box and store the box somewhere you will find it next christmas
With my suggestions by next Christmas arrives you would have your cards already done, a tree that is already decorated, gifts that arrive already wrapped , and have Christmas dinner out someplace (so you can eat it and enjoy it without cooking or washing up)
Also for the rest of your Christmas holiday season food that can be ordered online...you can sit in your living room, with something nice to eat, a glass of wine or a coffee, a nice movie on TV , curled up cosy on your sofa and order it in comfort online from your phone...and have it delivered to your home
Plan now so next Christmas will be hassle free and relaxing and more enjoyable for you
