It occurs to me you are missing the best person with which to consult RE your questions about your life path - your academic advisor. I would think this isn't a terribly unusual concern and it is probably in the school's interest to either get you over your concerns or get you moved into a more suitable field.

I think when people are very smart (and you must be to have gotten this far) they sort of automatically go to law or medicine. But there's a big wide world out there and just because you CAN get through med school doesn't mean you should. I'd talk to your advisor (or a therapist) and work your way through what you love about your work, what you hate about it, what you can change and what you can't. You may find doctor is a perfect role for you, but you need to work in not for profit (Medecins sans Frontiers), or you need to be a private physician for 1 rich guy, or you want to do research, or you need to consult. Cerner, for example, hires doctors and nurses to work with the computer programmers and sales force to improve their software. It sounds like an awful choice to me, but obviously it's a good choice for some.
