Continuing prescription?

I just moved across the country and am currently on two non narcotic prescriptions and I'm having some trouble finding a doctor to will write the prescriptions without trying to re-diagnose me or write different prescriptions. So I guess the question is does any one have any tips for finding a doctor to just keep writing my prescription or a place online to buy the them? My previous doctor was through my university and since I've graduated she won't continue to write the prescription.
