I'm not sure how the system works in your area, but I'm pretty sure we are all fairly close on a set of standards. Yes, like all the other previous posts have said, your age will hurt you on getting hired for insurance purposes, especially working for a private agency. And from my experience on even enrolling into a Paramedic program, especially in my state, want you to have some sort of experience level, ie pt contacts, number of calls and some want at least a year in an active EMS system.
In regards to your GED, who do you know with a GED, been denied entry into college? If its a goal to become a Paramedic, find out what the schools require, but in the meantime, gaining your EMT is still worth your 6 or 8 weeks. Plus you will have somesort of field exposure when doing your ride time. Another option is looking into your local fire departments on becoming a volunteer. Some don't require you to be atleast 21 and you will be able to maintain your training and gain your field experience. Applying for a volunteer FD with your EMT will make you a valuable asset especially if they are needing EMT's. Just my 2cents. Good luck and don't stress too much on your decisions.
