..I hear you..
.. I hope there was one person there who thanked you, told you how delicious everthing was, how beautiful everything was decorated, how they enjoyed the fun and laughter, the chance to bring family together.. to share the joy at Thanksgiving.
..if no-one even bothered to give you that little 'thank you'.. then, to hell with them..
..I wouldn't blame you one little bit for not doing the Christmas dinner... no-one should work all day cooking and cleaning and organizing and planning a big family dinner and NOT get a sincere 'THANK YOU' when they push themselves away from your table!! 
..nothing says you are being taken for granted and unappreciated as much as that!!
..my advice would be to totally go off on them..)not the little wee children, but all the adults and even the young adults (12+) that sat around your table ..and tell them off.
..that you no longer will host a dinner of any kind and not be thanked and appreciated! Period!
You deserve to be recognized and supported for your efforts.
..How much does it cost to say thank you??? nothing!!! Are they all so selfish, so thoughtless, so entitled that they don't see their ignorance and lack of common manners, enough to say thanks??
You need to tell them!
