Not sure what nursing career.

Hey everyone,
I'm new to the boards and new to this whole Nursing Major thing. I've changed my major so many times in the past year and a career in a health field like nursing is the only one that I have gotten excited about. It is something that feels like it would be fulfilling to have as a career. One thing that really scares me about it tho is the stressful and burned out part of it. I'm currently in a stressful job situation as a dog groomer for Petsmart. After 3 years i'm already burned out on the stress of dealing with crazy dogs and their owners while answering phone calls at the same time and dealing with 5 different managers. So many times i come home as if i ran a marathon and just emotionaly exhausted. Thats why i'm scared of persuing a career in nursing if it'll just make me feel the same way in the end after all the hard work of going to school. So my question is, i was wondering if there were some type of nursing careers that aren't too stressful? maybe working in an office? Any advice or comments I'd really apprechiate now. Hopefully I can stop changing my major finally.
