Fuuuuudge I'm tired and just started working as a nurse

26.5 weeks and just started working as an LVN last week and ladies I'm freaking tired. I wasnt in shape or ready for the job... I'm really regretting starting to work but need to as the student loans aren't going to pay themselves. My carts already halfway in the hall because my stomach is so big 😫 I feel like it's obviously not going to get any better. Any nurses out there still working? I was going to try and work until my water breaks but idk if I can make it another week.
