16 and graduated and wanting to take online courses for some kind of nursing job?

Ok I'm done with school already. Have been since Oct 06'. I really want to become some kinda doctor assistant or nurse or something like that. Something to where you don't have to go to school for like 7 years. I just want to take online courses at home. Maybe become a Certified Nurse or Nurse Practioner. I'm not sure. Do you know where I could look into something like that. How much it would cost and how long it would take to complete. I don't wanna take like a couple of years to do it. I just want to take the courses and be done. But I'm not sure exactly what I could be in that amount of time. I've been thinking about it and I kinda want to do it. Any ideas? Help! Im confused
Oh and yes I actually graduated at 15 actually 15 1/2 lol. :)
