I thought I knew what I wanted to major in, but I'm not so sure anyone.?

I think you should totally go to medical school, that would definitely open up opportunities for you. Something I thought you could possibly do is be a journalist! Many doctors write articles about different stories going on in the world of medicine. It would combine your love of writing and medicine. This is also something you could do all while being a doctor, and journalism and the news media go hand in hand. I think you should just go with the flow, but I definitely recommend medical school. I'd love to be a doctor, but I know I'm not nearly dedicated enough, and I'm rubbish at science.
