Reset messed everything up!! HELP!

Does this mean that you had made changes to the theme files? You should know that making changes to the theme files (like style.css) is not recommended. If you update the theme, then those changes will be lost. The recommended way to make changes to a theme is to create a child theme. Or, if your changes are only to the CSS, use a CSS plugin like Jetpack or Custom CSS Manager.

So, to solve your problem, most of the major hosts do daily backups. You can contact the support desk of your hosting company and have them restore your site from a date before you updated/reset your theme.
