Help with my future?

Hi. I guess I just need some support? I'm going into my junior year of highschool and I'm scared. The last 16 years of my life have been easy, and as a little girl I always told myself that I would make it to college and be super successful. Now that I'm older, I realize that college in expensive, and that my running and academic talents aren't as impressive of others, especially since I go to a big school. I just find it do overwhelming that the easiest years of my life are over and that I'm going to be an adult soon, and I'll have to be completely independent. I just wish I could be a little 9 year old again who could listen to Hanna Montana and never worry about her looks. I just can't believe that the easiest years are over. I find it scary that after I graduate, I'll need to decide what I do and pay for everything all on my own. I have a summer job as a lifeguard but that isn't gonna cut out the costs of college. My parents won't even be able to help with college because they're getting divorced when I move out, and they're swimming in debt as it is. Can I get some guidance? Thanks
