I know how you feel. I started on nights as a new grad on ortho unit with med overflow. I think this helped alot. I learned a good schedule (which often got out of kink) but had a flow I learned on my own. You learn how to handle pain and help your pts with ice, distraction, visitors and sleep. This is a demanding field but heartwarming when that special pt comes along that makes you smile inside. Don't be hard on yourself. Remember: Pain try to get on schedule if not working speak to doc about not adequate pain control. Uncontrollable crying could be a cry of despair/depression that you as a nurse can help identify for pt while on unit. You have your typical pain pts that no matter how much morphine or phenergan they are never satisfied, that you will share with all of us. I agree, put boundaries on the pt that calls constantly for tissues, water, and god forbid ice cream but is nauseated. Take a breath, it will get better. Good Luck!
