There's a kid going to WVU w/o a bachelors right now....but I think he came from the ivys and his dad is a physician. He also probably had near perfect grades and awesome ECs and awesome LORs. Unfortunately for most of us, we fail in one or more of these areas and thus, we need to complete a bachelors....
I don't know if this will help, but here are a few 'ideas' for interesting majors. You might try taking a class in each department (maybe you have already) and then see if one fits your interests...
Biology [Okay....maybe it's not 'unique', but it fulfills all of the premed requirements!]
Psychology [I think this is an awesome premed major! So many helpful classes 4 MS!]
Philosophy or Religious Studies [These are interesting majors that touch on the most important and fundamental issues humanity faces {i.e. ethics, love, hate, etc.}. Such majors tend to score very high on the MCAT due to the logical/reasoning abilities they acquire in their studies.]
English, History, Theatre/Film [Though a bit easier than Philosophy, these majors will also broaden your horizons and may also brighten your studies.]
Nutrition [Often overlooked, nutrition allows you to understand the human body on a very physiological level.]
Exercise Physiology [Like biology, it covers many of the prereqs....and you learn about the body's functions. Good major for DO OMT prep.]
Business or Economics [These majors would be very helpful for you if you decide to open your own practice in the future. Economics majors also tend to score well on professional exams.]
Political Science [This would also be helpful for you, esp. if you focus on the intersection of health policy, law, and administration.]
Edit: Also, see if your school offers a "Special Major". If they do, then you can create your own major from classes that you find interesting!
Good luck!
