I hope you are having a great holiday season and are remaining calm and enjoying it. I know it isn't easy. So many things going on this month and then trying to get work done, and the constant tax reform talk providing uncertainty. BUT it will calm down at some point. Just remember, life is too short to stress about things that don't really matter. The key is knowing what matters and what doesn't - that is true for both work and in life. As they say, "don't major in minors."
