It can definitely be overwhelming when you first start looking at college majors, theres one for every single job you can think of! The best way to start might be by writing down things that you like and things that you are good at, that can help you narrow your search. Like if you're enjoying a certain subject in school you can see what majors might relate to that.

The next step would be to find the nearest college to you and signing up for a tour. Most of the time the subjects you are familiar with from high school become whats called "Departments" and more specific subjects become the "majors." College tours are free, and give lots of information on what majors they have at the school and sometimes you can even meet with professors.
Don't be afraid if at the end of the day you can't pick just one! Most colleges will work with you if you decide to change your major later on, and some will admit you without one and help you to choose!
