I never envisioned myself being a nurse. I chose nursing because I knew I could find work being a nurse, it is a respected profession, and I will be able to support my family on the income. I am 34 years old and I am now finished with my first year of nursing and I must say that the more I learn about nursing the more I love it!
I did not know anything about the medical field before nursing school
so I can relate to you. In fact, I really didn't like being around sick people (because they can be so demanding) but my attitude toward nursing (and sick people)has changed so much since starting nursing school and doing clinicals.
Before nursing school I figured I could work for an insurance company or in administration as a nurse so I didn't have to be around sick people, lol. It is strange though, once I started gaining an understanding of why people are experiencing their ailments or whatever, my attitude toward "sick people" drastically changed!
I can't speak for you and tell you that you will love nursing. That is a risk/decision you will have to make on your own. I can say that for me, I am drawn to the nursing profession more and more each day. I wish you the best in whatever profession you decide to go into.
