Rising senior looking for help with college idea.?

I'll be a senior as of this August and I really need some college help. For the last few years I've been planning on doing ROTC in college, getting a Bachelor's Degree of Computer Science, becoming a computer systems specialist, and joining the USAF out of the ROTC program at college. I think the idea of military and technology based majors were pushed on me by my family, but that's a different story. Any how, I realized I really won't be happy being trapped behind a computer for a career. I'm the type who needs some people to people interaction. So I figured I'd do something in the scientific field. I love science and I've always done well in the subject, I think I want to become a pharmacist or a children's physician. Is this too drastic of a change of interest? I don't want to take steps in the wrong direction for the future I want. I used to know exactly what I wanted to do, but now I'm confused and my family isn't backing me up on the pharmaceutical idea. Should I stick with technology or move to science? Any sort of advice or suggestion will be greatly appreciated even though this isn't exactly a very well put out question.
