Career conundrums

I am stuck. It feels like I had a change of heart somewhere in between the months of September and December. After analyzing my career goals over and over again, I finally came to the conclusion that I would ideally like to be in a med school next year. I am stumped by this conclusion because I (and that is a BIG, BOLD "I") switched out of my major of pre-medicine two years back so that I could pursue engineering and avoid becoming a practicing doctor that my family had initially goaded me into. Don't get me wrong - I still do not want to become a practicing doctor; I just want to get my hands as close to operating and peeping into a human body as possible. I want to design medical devices whilst having a complete understanding of the physiology and having the degree to claim my astuteness in building one of these things. Aaah, now I am a little too late to apply to med schools for the next academic year along with being delinquent on a few of their pre-requisites. Wow, I never thought I would land myself in such deep quagmire! ...Unless... I find ways to land in my dream job without getting a degree, which might be difficult but not impossible... Boy, do I need some guidance or what?!
