PLEASE HELP!

Okay, I am new to allnurses and it took a heck of a lot of courage to even write this! I am a nursing student that has started my preceptorship. It has been a disaster. The very first day, my preceptor told me to just take a room. I just stood there not knowing what to do! First, yes, I know to go do an am assessment, but she didn't even introduce herself, muchless introduce me to the unit, how to chart, or anything. She is a very seasoned nurse and her grandchildren are even nurses, so I understand that she obviously knows what she's doing and has been in the field for a long time. But to blow someone off?

I asked her multiple times to please show me how to chart, or how to work with certain IV pumps that only critcal care areas have, and she didn't. She plays on her iPad constantly. It's terrible. The few things I have learned, other nurses have showed me. But on the flip side, the other nurses have me doing their work also, but it's never professional nursing experience that I am supposed to be getting. For example, I will be sitting at the computer charting, or even in my patients' rooms, and they will come and TELL me to go get VS, change their patient's bed linens, etc. I don't have time for my patients because I'm too busy with theirs. Everyday I go, I feel like I want to vomit before I walk in the building. I have spoke to my instructor, and she says that things need to be taken care of and this isn't normal, but that's it. The other day it was the worst it's ever been. All of the nurses huddled into an empty room and stayed for an hour while I was the only person on the unit besides the tech. There's nothing I can apparently do, so how on earth do I get self motivation to go to this place? My family doesn't seem to understand and says to "buck up" about it, but I am having serious trouble. No one else knows about this because I've never had a problem the whole time I've been in school, and I hate to complain to people about this.
