Can I do really do this??

I wonder if many others future nurses, or current nurses doubted their skills before graduating? I am in my final year and at times I find myself doubting if I am competent enough to be a nurse. I know it's obvious to feel doubtful when you are in a situation you haven't been in before. I also know I have made it this far for a reason! I just worry about have I learned enough yet in my ASN program to be responsible on my own with patients. I suppose the comfort level as a new nurse will come more once you find a job and becoming orientated with your own floor. Most new nurses are put on orientations with a seasoned nurse for a while too right? I know a lot of my fellow classmates feel the same but there are others that seem to think nothing of it. It could also be that clinical instructor who watches your every last move too! Either way is it normal to be nervous in your final year and will it get better?
