S.W.
Check out your local community college and your local fire department. They should have info on hand to direct you.
It takes about two years to get your certification might be more now days. This is a good time as you have no interruptions that would get in your way of studying. Apply for grants or such to finish your education and go from there. Make this your priority over a boyfriend if necessary so that you can take care of yourself and make a living. Be self-sufficient in this day and age.
Report back to us on your studies. We would like to hear about your success as an EMT. Shadowing in the hospital is a good way to find out if this is what you want. There might be a ride along program at the fire station as well.
There is always nursing, radiology or physical therapy as alternatives.
