My manager canceled my vacation less than 24 hours before my flight. Should I quit my job and go?

Guys, I'm seriously going crazy. I just got a message from my manager telling me that my approved vacation has been canceled, and I have to come in for my shift tomorrow morning.
I have a flight and hotel booked, and everything is non-refundable. I'm supposed to go on this trip that I've been planning for a very long time.
I've been working at this daycare since May. When I was hired, I was clear and upfront with them from the beginning that I needed a vacation from November 6th to 10th. They promised me it would be no problem at all and approved it back then.
I'm literally confused and don't know what to do, because this is my dream job. I've always wanted to work with children and I really love working here, but I feel what's happening is very unfair. I requested this vacation five months ago. I have no idea what I'm supposed to do.
