Well I can't offer much help I am still in school. I graduate this May and I am sure I will feel the stress and anxiety you are feeling at this moment. Everyone that I have talked to this far recommends doing thousands of questions. You sound a lot like me and you feel obligated to read and study each chapter in the review books, but you will waste so much time and energy. Doing several questions will help you focus on your weaker points and you can study from there. From what I hear prioritzation questions are key on the NCLEX. Keep up your hard work, use all the books but answer the questions. Check what your getting wrong and do quick reviews. Do not spend hours reading each chapter you will get burned out
