Nursing career

I have been through the nursing course and failed twice... first time were personal issues and having to deal with studying techniques, second time around had to do with me being active duty and some of my soldiers got in trouble and basically I haven't had enough time to study, but I wasn't far from passing at my finals... I am trying to apply to a 4 year institute, but they tell me I am ineligible to apply due to me failing my two nursing courses and now I feel like what I have done in my life is a waste... I always wanted to be a nurse and I feel that being an advocate for my clients' health and taking care of them would be my ultimate goal in life... now I feel like a total failure with no path to turn to...

Any advice if any? I am trying not to let it get to me and am searching for schools, but getting rejected up front really is fustrating...

Let me explain what I did: I failed Med Surg I ... then passed :) then I was taking Med Surg II and Pysch at the same time... passed Pysch, but not Med Surg II
