No job loss of skills...worried need advice.

I will start with I'm new on here...so if I am not posting correctly please let me know. Ok so I graduated in may 2011...Job for 6 months then nothing for over a year. Cant get an intview or call after applying to sooo many jobs. Here is a little history: I had a job in neurology private practice for 6 months the employer was a nightmare and the work environment was horrible. I loved my job but the interference of the bad boss and coworkers quickly overshadowed. I was a fairly confident nurse but after being told I had to forget all I learned in school and learn his way and through the repetitive mind games that were played...I lost confidence, skills and knowledge from school. I ended up leaving that job due to complications of pregnancy. So fast forward to jan 2013 and still no job. I have spent the past year searching and applying so many times I've lost count. Does anybody have any advice as to what I should do? I am no longer a new grad and I unfortunately lack more skills knowledge and experience than when I first graduated. I just feel if I could find a preceptorship or rn refresher I could get back to where I need to be and could possibly gain the confidence to apply to some jobs that open up at the hospitals. Which until now I have been scared to apply to many of them...since ones I have applied to have resulted in hr letters stated they are sorry I didn't meet the criteria. And really I probably don't...I feel at this point I have forgotten all skills. I am beginning to feel my degree is practically void. I worked so hard to earn it, but feel that bad first job screwed me up and made me miss my chance at a career in nursing. Other than going back and re reading my nursing school books...I just don't know what to do. ADVICE PLEASE. Before I go and apply at the local grocery store or something!
