This is a welcome change in attitude compared to some young whippersnappers we get here. Cad - no offense taken with not wanting to give your location, I simply meant geographical location, not exact address, just so we are clear. But anywho, It sounds like you have this well in hand.
I have a couple of free online courses you might want to take. Nothing great and earth shattering but they might help you sooth the EMS bug in you until you turn of age to take the class.

Anything on this website by the CDC - about half way down the page http://mphprogramslist.com/awesome-free-online-public-health-courses/
And everything from the university of Albany which is found directly below the CDC portion of the site. http://mphprogramslist.com/awesome-free-online-public-health-courses/
Paitent safety course as well http://www.who.int/patientsafety/research/online_course/en/index.html
Scroll further down from the University of albany and find the area where the Universal Class is listed and choose a class there that peaks your interest. http://mphprogramslist.com/awesome-free-online-public-health-courses/
The website that I have mostly linked to has numerous online FREE course offerings, not nearly college level courses but courses that everyone can take and learn something. I think that University of Albany and the CDC pieces might really be of interest to you.
I hope this helps.
