I have read your post with great attention. I know that NURSING is the greatest profession. But you say that when you in this job, you was not happy. Can i know that why you it was happen.By the way, If you not really feel happy in this job, sure, you should leave it. Because when man does not happy from his heart, she /he can't prosper in this profession. I think you should hear your heart and do what you want.
