But the C-E-O of the Canadian Psychological Association has some advice on how to stay calm and collected this holiday season. Dr. Karen Cohen says it's important to set realistic expectations.
"If you're go into the holidays hoping Uncle Jim and cousin Bob are going to get along really well this year, and mom is going to something different, and everyone is going to be happy. We may end up being disappointed because that's not always the way it works out," she says.
She says you should keep things in perspective if something doesn't go according to plan and try not make a mountain out of a molehill. She also says its important to pay attention to your own feelings and ask for help if you need it.
