At 17 years old, most employers understand that you don't have any experience. If you are applying to work at a fast food joint or whatever, they aren't going to care that you don't have experience.
This is an excellent job experience, as is being a wife, a mother, or anything else. When one is a wife, for example, you must make decisions(when to feed the baby, when to diaper the baby, when to take it to the doctor when sick, how to manage a meal, a husband and a baby.) When you are a hospital worker, you have major assignments that must be done correctly, or you will lose your job. I volunteer now in a local hospital, and I could build a resume around my duties, such as greeting people who are waiting for their loved one to return from surgery, having empathy, working in a community setting, i.e. working well with others, how to track when something is done ( when is patient going to be in recovery room for family to see them.) You get the point..I hope. Define your duties in different words than just going to work. When I had to do resumes, I made the resume fit the job that I wanted. I have always worked or volunteered, so I just expounded on the duties and experiences that were needed on the job I wanted. When I wanted a P.R. job, I expounded on my writing skills and my speaking skills. I emphasized a volunteer job I had on a newspaper (which wasn't a big job, but it should I knew the field a bit.) Homework assignment: write down everything you do at work, and then give it a different name that fits in a workplace. You will see a pattern forming of just how many abilities you have, which just had to be renamed. Good Luck. I know you will do well, because you will have the confidence to know you can do the job!
If you are lucky the form will not only ask for the bald facts about your background, but also ask why you think you are suited for the job. And that's where you go to town, telling them how great you are at doing all the stuff they are looking for and that you are a fast learner and the position is the one you've been hoping against hope to get!
