What to do with my nursing career??

I have been a licensed nurse since February 2012. I have my BSN. I graduated from a school in Iowa and moved back to colorado after graduation . I got hired working as a homecare/ private duty nurse in June of 2012. Ever since I have been unable to find a job that is better for my career! I don't get any benefits, paid time off or anything from my job. I am currently at the point where I need to start over but can't seem to get a better job anywhere. Does any one have any suggestion on what I could do. I am considering taking an RN refresher course to help get me some more hospital knowledge .

Thanks
