Another yes here!
I have never had a good relationship with my mother for various reasons. My brother who is 6 years younger, I have no relationship with. Certainly not my choice. I've made numerous attempts to develop a relationship with him, but he's never been interested. And I also have one aunt and uncle who I also have no relationship with.
So when holiday time comes around, I wonder why I am celebrating this time of year with strangers. At least that's how it feels. I am much more at ease at my work Christmas party where I feel I am among friends.
On a good note, I enjoy spending time with my grandmothers who are ages 88 and 89. I also have a great relationship with my dad.
Since all of the people I mentioned celebrate Christmas together, I try to hang around the positive relationships. However, things are awkward because half the group is people I feel I don't even know. And the mother relationship is a big source of anxiety for me.
