Unhappy and Quitting

Honestly, I'm not really happy with this work anymore, before I even knew that I passed the exam, I already have this feeling of being unhappy. I feel like quitting now. I can never be happy in this kind of environment, although I have fears as a newly registered nurse, I still want to pursue this career. I maybe earning something but this isn't what I want to be. Talk about pride and ego, but this isn't about that. Now that the results are out, I have decided to quit and go back to my original plan.
