First of all relax. Nursing school is a very hard task for all of us. It is hard not taking home work with you, try to seperate yourself from work once you get home, by taking a long hot bath, eat a lite meal and take a nap. When you awake, focus on reading that helps me out alot. When you start off your next day at your clinical, relax take a few deep breaths and just focus on being the best nurse you can be.
