Hi Jessica! I totally understand your anxiety but I wholeheartedly agree with the other posters.
I did, basically, all the "wrong" things in undergrad. I majored in acting, worked in sports media, and babysat for over a year after graduation before I discovered speech pathology and started a post-bac. On paper I only had one semester of relevant experience (outside of babysitting kids with comm disorders) before I applied to schools. I really believe that my unique background and personal essays (in addition to LOR, GREs, and working my butt off that semester) got me into the second best program in the country.
So keep doing what you love, explore as much as you can, and hopefully you'll see (as I have) that this field rocks because schools want people, and not just a collection of statistics. So far you are doing great!
