You sound like a good applicant although, I would think carefully before you decide to apply. Talk to other doctors and ask what they think about BS/MD programs.
When I was in high school I considered the same path but a few doctors told me that many of the doctors coming from accelerated BS/MD programs (in their experiences) were a little socially stunted. The BS/MD programs I was looking at were all 6 years.
If you're looking at 8 year programs, think about how much of a benefit it would actually be. Guaranteed admission to a medical school usually has a GPA/MCAT requirement. Also, you would be locked in to a certain undergrad/med school. Also, if you find something else you love in college, it wouldn't be a fun time to bail out of a program.
At 16 years old, sometimes you just need to take a deep breath and a step back. Just my thoughts.
