Are you holiday feasting on resentments? Well, stop. It's normal to feel resentful at a time of year when everything is supposed to be so ideal. And it's obvious that not everything is ideal and that we're going to be at parties and dinner tables with people who we research. If you can avoid people, places that make you physically sick because they've just been too demeaning and devaluing to you, it's okay to keep away.
Otherwise, be strategic. Six Sit next to the people that make you comfortable and accepted. And remember that this is a normal human feeling and put the emphasis on everything that you're grateful for, including who is not in your life and don't belong in your life.
