Just my opinion, but your holidays will only be "messed up" if you let them get "messed up".
I agree that people start "stressing" the holiday season waaaaaaaay to early. Christmas stuff gets seen right after Halloween (Thanksgiving always gets glossed over) and BOOM! Christmas is here.
I think that everyone needs to find a holiday activity they can mellow out with, or enjoy.
I always make sure I spend some time driving around town at night, looking at the way people decorated their houses.
Usually each Saturday in Dec is some activity, family party, friend party. Chirstmas Eve and Day is strictly immediate family.
I won't deny that Christmas is shoved down our throats, but we don't have to let it dominate everything, or ruin the way we spend the holidays.
