Who cares for the nurse?

We all know that nurses care for patients in all the ways that matter and more. But who takes care of the nurse when she/he gets stressed or emotionally drained? I like to talk (or vent) to my colleagues who help to build my confidence and help me to be a better nurse. They help me to see the realities of nursing as well as acknowledge the things I am doing right. Sometimes it's so hard to take care of ourselves but we always find a way so that we want to go back to work the next day. Perhaps you have a special way to de-stress after a busy day at work.
