Hi Cmot,
I suggest you just start school, take a few classes in various disciplines and make an informed decision. You will find that courses in college are incredibly different than the ones you took in high school, you will actually start to develop a REAL interest in something. If it is psychology, so be it! Just don't limit yourself to only psych classes for the first year, take a few different subjects and choose your major from there! I started college as an International Affairs major, switched to Speech, Language and Hearing Sciences and finally settled on Molecular, Cellular and Developmental Biology and Biochemistry (double). Strange path...yes. However, I took this path because I exposed myself to various fields and finally found the one for me and was very happy with my education. Also, I can guarantee my GPA as a science major was MUCH better than it would have been as an International Affairs major...because I was genuinely into what I was learning. If you like what you do your GPA will reflect it. As for a specific "med-school" major, don't think that way! Just make sure you take the required courses, EC's blah, blah, blah. Good Luck
