Hi StarWars117, Welcome to Cruise-Chat!
You might want to start by looking at Royal Caribbean and Carnival. You may also want to consider Disney. You are so lucky to have your parent or guardian allow you to pick your cruise. Since you have some time, take your time. One of our Administrators, Dave, happens to live near you. He probably has more insight about this, as he is the father of a teenager, and has been on many cruise lines.
Welcome aboard, and may the force be with you!
