Just do your thing and you'll work it out :)
It's not all about making fuss, writing some letters (well it might help some way), but I believe it takes you and your heart or soul even to get over it. Such was my thinking when I got started doing my own thing :)
You may face loads of stumble blocks, but just don't trouble your mind too much over that and flow with your own swing. You'll made it then.
When you discover how beautiful it is to follow your way let alone your future career in such a young age, you will understand that there's nothing in this world you could ever put into the box. :) Because you will love it, not for money, not for fame, not for prizes, not for profits, but for its uniqueness and oneness.
Maybe, one day you will be able to tell people about your achievement. And you will tell them that you sussed that things out all on your tod, which would be great :)
Good luck!
