I help teenagers and college students write them as part of my job. I would be willing to take a look at yours to give pointers? And I can give you some of the same advice that I give them, if it helps:
- Experiment with the templates in Word. (Or whatever you use for word processing.)
- Write a functional or skills-based format resume. You've not been working in a while, so you don't want to highlight that specifically. Summarize the amount of time you spent doing specific jobs without giving specific dates. (Ex: 8 years of customer service experience. You don't need to specify that it was 10 years ago.)
- Keep in mind to include any skills that you have used in the time since you've worked - any groups you've been part of (professional or hobby) could have marketable skills. (Not joking, I know a lot of people who have used gaming related skills on their resume - I'm one of them.)
- Google it. If you check online there are TONS of examples of other resumes people have shared, there are also literally hundreds of sites that give free advice and other free templates you can try out so that you can build something that suits what you are wanting to do.
But honestly, I'm willing to help.
