Where to go or where not to go?

There are so many possiblities about where to go in life and God does not seem to be helping me pick one whatsoever.

I have been stuck in a "what should I do with my life?" phase for several months now. I decided last fall to not take the MCAT this spring and therefore I will definitely not be going to medical school in the Fall of 2011 as originally planned. I used to have my life completely planned out: I would get my M.D. and work in a clinic in Houston and get married to a wonderful man of God and have 2-4 children who are adorable and brilliant. Well, I'm not so sure anymore. I'm learning to trust in God, but He's not giving answers. I need to decide something soon - try for med. school? try for P.A. school? Get a masters in something unrelated? something related? Medical? Non-medical?

I've lost my passion for science, kind of. I am tired of learning this stuff. Usually, it doesn't make sense to me. I just want to help people. I guess knowing the science behind it helps me help them, but it's hard to see that right now when my professors simply ramble fact after fact and don't tell me why it matters.

God...give me some kind of idea!
