When I was in high school, I had no idea what I wanted to be. I went to community college after graduation and took several classes that I thought might interest me to try them out, while also taking some general education courses. I found that I LOVE psychology, so I transferred to a 4 year school and got my B.S. in psychology. I would recommend the community college route to anyone; it's a LOT cheaper than universities. Transferring was really easy too, the counselors that I worked with were wonderful.

One thing to think about, did you ever take your SATs? If not, you may have to take them depending on where you decide to go. X-Ray tech might be a good field for you if you are interested, or Ultrasound, or Medical Assisting, something like that if you are interested in the medical field. I would say do some kind of school...I don't know if anyone who has ever said that they regretted going to college, but I know lots who regret NOT going.
