Taking Nclex for second time: where to begin?

Hello all. I took all 265 questions on June 29, 2015. It took me 3.5 hours and I went in there and panicked. took one break at 115 questions to cry and take a deep breath. I got 30-40 SATA/arrange/EKG type questions. I knew i wasn't getting enough of them to pass. I was so thrown off by the medications.. Everything i thought i knew went out the window when i read the questions. I always did in the 850-950 range on HESI exams. I did not take Kaplan, although i did several hundred of their qbank questions. I am taking the class August 10-13, and plan to test around August 20. I also have the HURST lectures as well. I just am so overwhelemed and feel very down on myself. I WANT to study and know i need to.. but i am so afraid of studying wrong that i do not know where to begin. I want to have a lot of studying under my belt before i even get to kaplan.. this was the only time the class was offered and i still have to drive 3 hours away to get to it. I just need some advice on how people studied their second time to pass. Just dreading going into that test center again...
