You’re feelings are totally valid and normal. I think your biggest hurdle will be to convince your parents that you don’t need to have your life planned out at 17.
From your post, the one thing that jumped out at me is that it sounds like you might enjoy biomedical engineering. Not only does it combine numbers and biology, but there are also many business opportunities as well.
Perhaps check out WPI’s website. See what majors interest you. It is a very collaborative school that requires projects at are interdisciplinary, has a fairly open curriculum and requires internships. While I’m not saying that’s the perfect school for you, I think it might give you some ideas of how different disciplines can work together and what opportunities are available in certain areas of study. It would not be unusual for someone to study robotics, biomedical engineering and business. Or delve into financial technology, entrepreneurship, or economics. Everything is a possibility, just look for schools where either you don’t have to pick a major or it is easy to change and that offers things that interest you.
