I Need Help

I graduated nursing school from India in July 2012, and I have given the test 4 times already. The first time I gave the test was in April 2013, I didn't care for it and without studying I went in to give the test. The second time was in Nov. 2013, I went thru Saunders once and did only the questions from Kaplan. The third time I took hurst review, I learned a lot and I improved on the questions (I was getting 50%). By the third time I had forgotten a lot of what I learned in nursing school, so hurst helped me with core content. When I failed the 3rd time in April 2014, and got my result back, I was above passing in everything except "Safety and Infection Control" and "Basic Care and Comfort". I continued with Hurst and gave the test for the 4th time in Sept. 2014. I got my result back and i did worse than the 3rd time. I'm "Near passing" on half the things and "Below passing" for the other half. Its been 2 years now, and I'm drained out. Ive spent over $2000 on prep material, including the apps for the phone, prep courses. I just don't know what to do, i have no energy to study alone, because i put myself in a negative bubble and don't do anything for hours. I haven't found a tutor in my area that can sit with me and help me on my weak points, and I don't know what prep course to do now. I need help, I don't know what to do or how to study, I feel like giving up but I have family and friends who remind me that I failed it 4 times.
