Need Advice - Continue RN or drop to LPN Program

If anybody has any advice I'd certainly appreciate it.

Ok here's my story. I'm 26, have a Bachelors Degree in Business Information Systems and went back to school for nursing about 3 years ago. I have all my prereqs done, and got accepted into the highly competitive RN 2 year degree program. The first few weeks into the program I felt totally lost. I came fresh out of business school with no healthcare experience at all, and clinicals and labs were so stressful I would make myself sick. So I talked to my advisor, who was also my lecture and lab prof. She said not everybody makes it in nursing and I should go get experience as a CNA. She also was very negative toward about 80% of students in the class... which made me definately feel stupid and brought what little confidence I had to zero. The thing was, I passed all the skills easily in lab, got A's and B's on all the tests, and got an A- for my final grade on the care plan portion. I ended up with a B in the class (probably 40% of the students failed) but did not return the next semester because I still did not feel up to par doing what we learned. I got my CNA license and worked at a nursing home for 6 months, but due to financial constraints and a bad work environment I pretty much gave up on that.

Now, I'm getting the itch to go back and finish. I really want to learn things from the ground up, and be proficient in all skills. I'm wondering if I should try to get back into the RN program, which I know is possible I've talked to admissions, or just start over and learn everything new in the LPN program. It seems like a waste of money because it will take twice as many credits to finally graduate from the RN program, but I don't want to feel hurried and incompetent like before. What do you think???
