What should I do?

I honestly do not even know where to begin. Initially, I started off at a 4 year BSN program and then moved to an ADN program because I thought it would be a better option for me. My ADN program let me take prereqs with the actual nursing course itself. So my first semester I was taking NUTR 101, NUR 101 LEC,LAB, AND CLINICAL, AP 1 LEC & LAB. Needless to say, it was a lot. I passed both of my other courses, and had a 76.0% (needed a 77.0%) to pass the class. This left a permanent D in my transcript, even though in the class I had a low B or high C. I was devastated, not only because it was 1 percent, but because I put in a lot of work. Now I am doing psychology back at my university, but I know my true passion is in nursing or even something related. However, I keep getting the reminder of failing by one percent. Relatively speaking, I did pretty average on my exams, but I am not going to lie I did not really have a lot of time and more often than not did not complete the all the readings for the semester. I just do not understand the way the questions are worded, granted that these are the "dreaded" nursing style questions. However we did a practice exam on NUTR and my instructor did say that a lot of this information you have not covered, so keep that in mind. I got a whopping 34% while the rest of my classmates were getting 40s and 50s. To others it only looks like 6% , but what if this happens on the NCLEX. I honestly can say however that I know I can do better, and obviously not take other classes with nursing. I am only 20 years old, and will be graduating next year with a bachelors and associates in psychology at the age of 21, so I guess I do have time to decide. My ultimate goal is to be a NP or CRNA. Should I do an accelerated route again and focus entirely on that or should I apply to an ADN program and start that. What do you guys think? Any help, even if it is super simple is appreciated! Thank you!
