Have to do Resume, need help, never Done it Before

My class starts tomorrow and the teacher wants us to bring in a resume. I don't know where to start, I don't know what to do, I'm really stressed out about this, I've had so many jobs over the years, mostly dead end jobs (restaurants, retail, etc) I've taken my time with school, I've been in school for nine years and just recently I got my associates degree. Can someone please help me out, I don't know what to do. Plus I don't have any info on my past jobs.
