Need nurses' point of views

I am a nursing student, and it's becoming more aware to me that I could have chosen the wrong major. Nursing has been the only thing to ever interest me or make me feel like I would be doing something worth while; however, in my past experience I do NOT do well with long shifts or not getting enough sleep. I tend to have panic attacks more easily and my menstural cycles get all out of whack(sorry males) when I am sleep deprived. When I look at other majors, nothing seems interesting. Is there any way that nursing could work for me??
