Nursing frustration

Hi, my name is Laura.

i am a nurse of almost two years of experience in Home a Care for fragile children. I stared working on my CPN (Certfied Pediatric Nurse) exam prep. Before becoming an RN I worked as PCT in two hospital settings for 7 years. Even though it seems my career is moving forward I carry a big burden of frustration. When I finished school I moved from one state to other taking my NCLEX in the new place and passing successful with 75 questions, but my first experience as Graduate nurse was a complete disaster. Making a long story short I quit my graduate program because I panick. It was the first time in my health career that fear made me step back. It's been already two years, but I can't overcome this. I feel stupid, sometimes unworthy with a heavy burden of frustration. The worst thing is that now it is very difficult to go back to the hospital. Even though I am grateful because I have a job it is not the best experience since the agency pays so little (I am making the wages of an LPN being an RN) and the benefits are horrible. I regret one and a thousand times quitting the program. What can I do? Where Can I get support? Is there a nurses association I may get in and have some help? I would like to know
