To answer your question about whether or not assisting people with their personal needs, it does get easier. Every time I have to do peri-care or anything else invasive, I treat it as any other medical care while ensuring the patient is comfortable. Personally, being a CNA did not strengthen my desire to be a nurse. It's a very tough job, physically and emotionally. If you're undecided about whether or not nursing is for you.. Think about why you want to do it. Is it all about finances? Do you truly care about helping those in need? What is the driving force? You can also go and check out the nursing program at the school you want to go to. Also, talking to a nursing advisor at the school can help clarify the route you may need to go, academic wise. Again, volunteering and job shadowing are great sources of information. Good luck on your decision!
