Can I sue a school district that offered a job, allowed me to complete "new hire packet" and rescinded the job offer?

I went to job fair where we were told to stop looking after we accepted an offer and 2nd interview. I was offered a job and accepted. I turned down interview offers. The HR sent congratulatory notes and "New Hire Packet" which was completed and successfully submitted. There was a break in communication for a week. I wrote them and never replied. I went to HR offices after 2 weeks of silence There I was told they could not continue with the job offer because I resigned in lieu of nonrenewal about 2 years ago. Why the job fairs-2, interviews, job offer, congratulation, new hire packet, etc
