When should I quit my job?

This is my first pregnancy, it's been awful, and work makes me 100x worse.

I work overnight at a bakery. Usually I have to leave my house at 1am, sometimes 11pm! I work an hour away from my home.

My morning sickness is always so terrible when I am at work, but on my days off, I feel GREAT!

I never get enough sleep because of the hours, and it's a job where I am required to stand the awhile time. We also do not get set breaks. When we finish the work, we can leave. We can "ask" for a break, but you get judged. Just like I'm allowed to sit down, but when I do, I get judged.

I am 15 weeks now. My household would remain financially stable if I quit.
