Anyone graduated from RN school who had serious doubts going in?

After two years I have finally finished my prerequisites and am applying for the RN (ADN) program this week. That being said, I'm having serious doubts now about whether I really want this. I am exhausted from an intense double dose of Chem & Algebra during a five week summer session. I am struggling to get back into a "study" mindset with my A & P II course that just began last week. I feel like I could easily sleep uninterrupted for several days (or more). Worst of all, I feel completely unqualified to be making any life-changing decisions in my current state. I just don't know if my feelings are coming from my heart or if it's just the fatigue talking.

I have found several helpful posts here where students have shared similar concerns, but would also appreciate advice from someone who has made it to the other side.
Has anyone gone through this and gone on to graduate? Did you have any regrets or find that the "flip-floppiness" just sort of dissolved along the way? Thanks to anyone willing to share! I think another point of view would be very helpful right now.
Well I just graduated in May and was very unsure until about my last semster of school. It is a life changing move but being a nurse gives you so many different options.
I felt this way all through the program. All through my classes my instructors would talk about emotions, and coping, etc. My classmates would always talk about how they felt in class and it was always feelings, feelings, feelings and I just wanted to scream. We'd do really stupid exercises like sit in a circle and say our names and introduce ourselves wasting entire class periods. I was so annoyed and disgusted that I dropped out and got another degree but since I was only 1.5 years away I went back and finished up. Anyways, I graduated and the ironic thing is after 3 months I of applying EVERYWHERE and passing the test from hell I still can't find a job.
