Future?

Okay so I have completed two years of college, I am currently a Health studies major trying to get into the nursing program at utica college. I m taking one of my a and p classes over this summer because i didnt get the grade i needed for the class. I need to take one more also so i dont know if i will be able to get in the program. I f i dont get into the program i dont know what im going to do with myself because this is the only thing i want to be a nurse the only thing in my life that will never hurt me only make me a better person through different experiences everyday. The last time i spoke to the nursing director she told me to think about changing my major but i cant if i gradute as a health studies major where will i get a job at no i cant do that. i need security. i need to know that soon as i gradute that i will find a job,college is hard enough to graduate and not know what to do. I want to dissappoint myself and my family they are countingon meand i cant let them down. Everytime I think about my future and how its at question right now i think about how in middle school i wanted to be a chef. But there werent culinary high schools yet they came out once i had gotten to high school already. i love helping people and i fell in love with birth during a high school internship in the hospital. I love making people happy,helping them feel better through care,soothing food, and a good pep talk.i currently need a pep talk.
My question to self sometimes is : is everything going wrong with nursing because i need to rechase my past dream of being a chef?
