How bad is an "F" for a science course

[cookie91]

Hi everyone. i have come to a stressful time in my college life. i received my first "F" in chemistry because it was actually a "c" and for financial aid reasons in order for me to retake the course next semester i must get an "F" for financial aid to cover the class again. so i re took the class and got a "b". Now again i am just finishing up for anatomy and again because i went to the wrong class same lecture than transfered to the new professor messed me up and now i see a big fat "F" in my transcript again because i will be getting a "c" i am so depressed! ... now the school i attend has a nursing school but my heart is in another university. i really really want to go. lets just say hypothetically i do excellent from now on. How bad do this "F" look in my application is my life as a nurse over?. in the school i attend the director spoke to a group and she said that they do not look at the repeated course you pass. they look at the first grade you got when you first took it. i need serious help please. what can i do?
