I don't even know what I'm looking for here. Advice, similar stories, people to complain with... Just venting

So I got to work today and found out that I'm getting one day a week cut off of my schedule! I work part time so I'm going from 4 days to 3 days. And I know that she just cut it because I requested a holiday off( I work somewhere that's 24/7) and it's also the ONLY holiday I've requested off in the 2.5 years of working here(I'm talking thanksgiving, Xmas everything!) I'm just so fed up right now. I really just want to quit and enjoy the holidays with my family and look for a new job in January. We *could* afford it. It wouldn't be the best thing for us but it wouldn't break us or anything...
