Find new traditions that work for you. Question how you have done things in the past that have brought distress and discontent. Don’t like going to your in-laws for a week? Then don’t. It is okay. This is your life and your family.
For example, I was working with a client who got so stressed out about preparing a big meal for Christmas Eve and Christmas Day, which had been a tradition in her family for years. So she decided to order take out on Christmas Eve. Her husband picked up the food, they made a fire and everyone enjoyed a wonderful, stress-free meal in their living room by the tree. Preparing the Christmas feast the next day was much more enjoyable for her, too.
