Is it natural to worry?

I'm on my way to hopefully become a nurse but I stress daily that I don't have what it takes. I want to be a nurse because I love helping people (mainly children) and because I want a job with different traveling opportunities. I worry that nursing school is going to be way too hard and that I don't have the right kind of personality. I do get shy and I always second guess my decisions before I carry them out. But one upside is that I do tend to work better under stress. Is this natural to worry like this?
You are wise to worry about making it in the nursing field.If you are already accepted to the program... you have been evaluated by people who have a pretty good eye as to what it takes.Your shyness and indecision should quickly evaporate when it comes to advocating for your patients.Nursing school is the hardest thing I have ever survived.. keep us posted.... private message for any support you may need.
