First night working on my own at a SNF

So today was supposed to be my first night working alone after 7 days of orienting. I spent each day and shift on different stations. Never really got to know my patients during orientation. Shift was supposed to be from 3-1130 PM. I didn't finish til 130 AM. Took no breaks, not even a 30 minute break for dinner. Had about 30 patients with many on PRN pain meds. They count down every second and make it seem like a life and death situation if they don't get it at the time they're supposed to. For some reason, I just don't ethically feel good about this sort of environment or the nature of the business. Have a job interview in two days for a Cardiology Clinic. REALLY hope it pans out. They seem to like my work experience and think I would fit in great at their clinic. What a day what a day....hopefully its one of my last days here.
