I remember this feeling! It feels like a very big decision that creeps up on you quickly. As others have mentioned, I'd recommend thinking about your passions, interests, and what is important to you. Some colleges and universities offer an "undecided" program where you can attend your first year and explore a variety of different classes to find what you want to pursue beginning in your second year. A lot of students change their majors once they've already selected them after a couple of years too because they find something that interests them more - so don't feel too stressed that your decision has to be perfect. There may be some subjects or careers that you haven't had any exposure too and college is a great place to start learning about them. Some people have the impression that shouldn't change their major as it may extend the time it takes to complete a program, but in my opinion, it's a small price to pay to ensure you don't end up doing something you never liked anyway!
Best of luck in your decision.
