I fell in love with math in junior college because of two professors who genuinely loved the subject and spent quality time with our small group of students - treated us like fellow-researchers. A big part of why I loved it was the group of students who studied together diligently every afternoon for two years. I was good at problem-solving, and the prospects were good (1980's), so I went the engineering route. But I went back for a Masters degree in math education recently and again enjoyed the higher level math I took - to a point. I got to some of the graduate-level courses and realized I could learn it with effort, but the younger kids were far faster in absorbing the ideas than I was, which added stress and took some of the fun out of it. Now I enjoy learning math at my own pace.
While you're young and still deciding on an educational/career pathway, go as far as you can with math if you think it's for you. Pick a mentor, a good high school teacher or college professor - or a great grad student, and ask them to show you what "turns them on" about the math they're doing. Help someone complete a proof to submit for publication, take notes for a professor who wants to publish. Know who the great teachers/professors are, and arrange your schedule around taking them. Get to know a mathematician closely. Look at taking the watershed college-level courses, such as Foundations of Advanced Mathematics, that are required to proceed further. Join a math club. It sounds hokey, but these are students who can help you find yourself, and the club's professor-advisor is usually a great resource.
By the way, when I was in high school, I hated geometry but loved algebra. In undergraduate college, I fell in love with calculus, but I didn't care for statistics. I think every mathematician has his or her favorite area. There are so many facets of math, that it's probable you haven't even found the general field you'll like yet. Hang in there, and best wishes!
