I do spend Christmas eve with my family but because that day is no longer the big event that the whole month of december has been leading up to, I don't feel the pressure of it all having to go smoothly. If it gets too much, I'll excuse myself and head home. I know this won't work for everyone; my family is small and we live close together. But just this simple change in my mindset has helped me personally reduce the anxiety that the holidays would give me every year.
