I agree with everything Linda said. I also would like to add that I think that being at ease in conversation is a gift for some people, but I learned it as a skill. I'm naturally a bit reserved and stand-offish until I know somebody WELL.
The first patient my first year in nursing school
- I paced up and down outside her room for SEVERAL minutes before I worked up the nerve to knock and enter. I found, and perhaps it would be helpful to you, that "The Nurse" (e.g., ME) is almost always welcome. That's a good thing to have in mind. Also, having that role of "the nurse" helps in conversation, as well.
Also, yes, many nurses have to overcome squeamishness! One of my classmates seriously questioned her choice of careers whilst still in school - if anybody threw up, or pooped, she threw up and cried. She got over it and she's a great nurse.
I think maybe you could get an idea of how much you'd like nursing by taking a job as a tech (or CNA or whatever they're called in your neck of the woods).
And agreeing with Linda again! Yes, we were all scared as new nurses. I think anybody who isn't is going to be a scary nurse!! And yes, it's still scary from time to time. I remember emailing my best friend from a computer on my lunch-hour that I don't like being a nurse, I'm not good at it, and I want to go home. That got it off my chest, and I went back to work and carried on.
One of the many really cool things about nursing is that there are SO many facets of it. If you don't like one thing, then you can try another. It's amazing, really.
Good luck in your decision and with your education if you decide to go for it!
