I always wanted to be a nurse, but ended up getting a teaching degree and regretting it. I think that if you feel strongly about being a nurse, you should do it. I am now back in nursing school (almost done!
), and am so happy that I am finally doing what I originally intended to do.
Don't worry about the pig. Find a way to get through that part. I have found there are things that make my toes curl (burns, orthopedic surgery, eye surgery), so I know I won't practice in those areas. But there are so many things I LOVE--like doing something small to put a patient at ease, or getting to try a skill I have never done before (I was so giddy the first time I checked NG placement--silly, I know).
There are so many AWESOME things nursing and nursing school have to offer. All those pre-reqs are the sludge you have to walk through to get to the good stuff!!! You are almost there......
