I think you already know what to do, you just need reassurance.
I say go ahead and take the new job. You said it yourself, they will cut nurses down in the future, so why waite for the future, why not start now. Yes, it's difficult being the new nurse because of how people will treat you, but you'll get over it like your first time at your present location. Before you know it, you'll get the hang of things. Even though it's an hour away, it's better to take on the job now, instead of waiting for them to let you go. Good luck
