burn out in first yr

I currently work on a very busy, very stressfull stepdown unit. While it is not my dream job, I feel like I have learned alot and developed my skills. However, I am worn out. The hospital is having budget issues so we are now taking more pt with less help, without any incentive. We are not even getting our raises this year. I feel so tired and stressed all the time. The patients on our floor are very heavy and often have psych issues along with the medical issues. At least once a week I am getting hit, scratched or kicked by a combative patient the other nights I am putting confused people back to bed or restraining them to keep them from pulling out lines or catheters. I am exausted, Most nights I dont even want to come to work and I wonder why I chose this proffession.
Again this is not my dream job, I really want to work in neonatal or OB. I realize this is a stressfull area also but its more where my heart is so I feel I will enjoy it more.
I feel like I go home beat up night after night. I feel burnt out. Is this normal to feel this so soon into my career Ive been working for 10 months now.
My husband thinks I should look for another job but there isnt really much out there in the area I want to be in and I know I should just be grateful I have a job. I just wish I was doing something I actually enjoyed. I have nightmares about this place.

Thanks for letting me vent.....
