I find myself in a similar situation. I've been here for a year and contemplate everytime I walk through the door whether or not I should stay. Good luck to you - I wish I had some advice.
I worked in NICU straight out of nursing school in a large urban teaching hospital. I think the hiring of new grads in these specialty areas has alot to do with the institution wanting to train new staff in their own way...in other words not getting "old" nurses with bbad habits from other institutions.
