I need help with how i should fix my nose?

my nose is very messed up. it is big for starts, and pointy. it is also very crooked in the middle of it, and it has a a big bump on top of it(its not anything to be worried about, its just part of the shape). i really don't know what to do. i am only sixteen and my parents keep telling me to wait till im at least 19, and i don't even know if they will let me do it. PLEASE, don't put mean answers. i get teased about my nose all the time and i really don't want to hear it anymore.
