Answer:
Hmmm! This hasen't happened to me before... I would just go to my room and take some time for myself to cool down. Maybe read a book or take a walk. Text or call a friend. Do a craft. Sew. Knit. Think of that day as YOU-day. Who cares about presents and family time?! Do whatever makes YOU happy :))
Hope this helps!
