I'm glad you had a stress free Thankgiving!! YAY!!
I get the impression that you feel some obligation to see your mom during Christmas. If you truly feel you must do that (even knowing how the visit will go for you) maybe you can make a Plan B. If (or when) things get too difficult and frustrating for you, you can have a plan to go somewhere else.
I truly hope that you are able to get through this time relatively unscathed. Be good to yourself for you are the one who has to live with yourself
Hugsss
