I was in the ER for 12 hours....with a broken foot...

I was in the ER for 12 hours....with a broken foot, couldn't walk, and did not eat a single thing. I asked multiple nurses if there was anything I could have and was told by some since they're not my nurse, they couldn't provide me with anything. I told another nurse EXACTLY where my nurse was (on the other side of a curtain) and she said "okay, I'll tell her" then walked right in the opposite direction, she never came back to check on me, or do anything. I've never felt so blatantly disrespected. How is it that someone tells you they've been around for half the day, and has not had anything to eat or drink but a tiny cup of water, and you no effort to help find my nurse for me when I'm hungry, thirty and cannot do for myself?
