Frustrated LVN cant find a job. What to do?

Thanks for the suggestions. I live in Los Angeles, CA and most of the interviews I've done go really well. They say I will call you in a week for a second interview but never do. I applied at a snf and the DON seemed really interested in hiring me. I was told by the HR staff they would do a background check and call me in 3 days, I never got the call. So I figured I would be more aggressive and call back to see what happened. When I called I was told to call back in a week, because administration was on vacation. When I called. The DON just said I'm working on it and hung up on me. Today had an appointment at a registry when I got there know one was there, so I called from the front door the manager told me they would be out of the office the whole day, but know one said that when I talked to them on friday. I am so frustrated beyond belief. Can the economy be the blame?

I live in Los Angeles, CA. In LA they rarely offer LVN'S a sign on bonus only RN'S
