However, I think the whole thing sounds like a disaster. I'm sorry you've been treated poorly since going to night shift (and I do think a couple of your examples are beyond "putting your big girl panties on" when they happen day after day) - but if there's truly no one else on your night shift who is fit to precept you because none of them have enough experience, that likely means that your current preceptor has been doing nothing but helping new grads for who knows how long. It can be very rough, especially when also carrying one's own assignment, especially when there's no end in sight, and especially if you know they aren't going to stay around.
I'd cut the preceptor some slack -- a new grad has absolutely NO idea how difficult it can be to be precepting constantly with no end in sight, and no visible results because the new grads just quit as soon as or even before they've had time to become competent. Learn what you can from her, overlook the rest.
As far as your manager -- going to her with feelings isn't the most productive approach and doesn't make you look like a grown-up. No wonder she told you to put on your big girl panties. It's your job to manage your feelings, not your manager's. If you must go to her, ask her how she thinks you're doing, what she identifies as areas for improvement and if there are any areas of major concern. Rather than complain that your preceptor "yells and has a fit" (which I find difficult to believe), describe the exact behaviors that you find objectionable. Perhaps the preceptor's negative feedback isn't constructive, she uses demeaning or condescending language or her body language is off-putting -- perhaps your manager knows this, but doesn't have anyone else who can precept you, so she's frustrated. But sharing FEELINGS rather than FACTS with your manager is unlikely to result in good outcomes unless you have a "touchy-feely" manager.
You're two weeks from the end of your orientation. Identify your resources now. The unit secretary can help you with issues involving paging physicians, scheduling tests, finding results and all manner of other things. If she can't help you with something, she likely knows who can. RTs, PTs, pharmacists and CNAs can also help. I've met few CNAs who cannot tell me where to find some rarely-used piece of equipment. The pharmacist can tell you whether these two drips are compatible and the RT can explain vent settings, CPAP, blood gases and any number of other tasky things and critical-thinking concepts. Find out where your policy and procedure manuals are and how to use them.
The first response held a true gem of advice. "Same problems, different faces." The grass truly isn't greener.
