Honestly I would make sure you have a job lined up first... Unless you have other means such as family to fall back on in case you don't find a job right away.
I'm a nursing student, but I still work in admin. We put a job offer out for a minimum wage warehouse worker, and I was getting applications from people who have bachelor degrees from major universities. It was real eye opening to how bad the unemployment rate is right now for certain folks. Granted I do live on the west coast though, and we have been hit really hard.
What I'm saying is you can guarantee that you will find a job as soon as you would like. I do wish you the best of luck though!!!

Just keep applying, and try and stick it out a little longer. You obviously are a strong hard working person if your a CNA, and nursing student. Just remind yourself that.
