The same thing happened with me. Although it might not be what you want to do, nursing homes and rehabilitation hospitals will sometimes hire new graduates. I was lucky enough to be hired as a new grad at an acute rehab hospital and although a lot of places don't consider that med surg experience it's better then nothing and you leant to prioritize and deal with patients. Also if you really can't get a nursing job try to apply for a nursing assistant job just to get your foot in the door. A lot of hospitals are more likely to hire from within!
