I'm sorry they impose upon your feelings that way
Please try to have a good holiday... how they treat you isn't who you are. Be who you are, or even who you want and plan to be! Act the part, be the adult, don't be the mother or dad... just be, today!
Make some plans...at least one, and follow through..and while you take that walk or watch that movie, think about how great it is to be doing what you want. TC.
