If there is something you can do to make your holidays better, I would recommend that you do it. Place a time limit for visiting your HP, find a neutral place (not in the hoard) to celebrate the holiday, limit the amount of gifts exchanged. I know that my Christmases became much more enjoyable when I started to stay with my brother and his wife rather than stay at my grandma's with my mother while I was visiting for the holiday. Focus on what you are thankful for and let everything else melt away.
Hugs to you all!
