No Houston CNA jobs?

I got my CNA license back in September, but I haven't been able to find a job to save my life. During the fall semester, they didn't want me because I couldn't work full time. Now, I'm out of school until I get into nursing school, so I started applying for fulltime jobs starting in October and updating regularly. I call in to check on status, and visit the nurse managers/human resources, but to no avail. I've applied to several nursing homes around the West University area, as well as St. Luke's and Memorial Hermann. A big catch-22 is the face that many places require at least 2 years experience, and I have about 6 months. They also really want prn, which is ironic because they wanted fulltime while I was in school. I'm so desperate that I'd take prn, but all I've gotten is "We'll call you if we're interested." Any suggestions? Thanks.
