Angela - as a degreed engineer with two engineering majors, I can advise you that you don't need to make your specific engineering major choice right now. My recommendation is that you find a university or college with a strong undergraduate engineering program that offers a multiple number of engineering bachelor degree majors. Generally speaking, your first one, and usually two, years of engineering coursework is common across almost all of the engineering majors. Taking those course will be better help you to identify your own strengths and weaknesses as well as subjects that interest you. Generally, by the end of your Freshman year, or, by mid-Sophomore year, you'll have a good idea of what engineering major to declare.
In my own case, I started out thinking that I wanted to be an aerospace engineer. However, after a year of university general engineering classes, I realized that aero was not a good fit for me and the career that I wanted to pursue. So, I declared for Biological Systems Engineering as my B.S. major. Then, later in life, I went back to school and received my Masters degree in Environmental Engineering.
Regardless of what engineering major you declare, you will find out as an engineer that many engineering disciplines work in conjunction with one another. Best wishes as you start your journey!
