I am 15 years old. I need jaw surgery because I have and underbite, but because it is not just the teeth I don't need braces. It is my whole bottom jaw that needs surgery. I want to become a classical singer but because of my underbite it has become very complicated to sleep, breath, talk, and sing. I can't stop thinking about my underbite, it just hurts so much. Anyone that can answer, please do! But... I have a fatty acid oxidation disorder and I am worried about having surgery.
