Study engineering. I've known successful doctors who started in engineering, but no successful engineers who started in pre-med. Engineering can apply to anatomy quite well, and opens up more areas of medicine such as prosthetics, forensic medicine, physical therapy, and creating new therapies. An understanding and feel for systems is a wonderful thing, and the math is good too.
Besides, you can do anything you want with an engineering degree: teaching, anthropology, computer programming, writing, banking, politics, and of course medicine. I've known people in all of those fields who started with engineering bachelors degrees.
