Facial Asymmetry Very Uneven Bone Structure?

im a 22 year old male and i have always been bothered about my looks i have been told by many that i am ugly and i know i cant fix that but i thought maybe atleast i could improve my appearance by evening out my face mainly the left side of my jaw bone is bigger than the other and my mouth is slightly leaning to one side i think braces may help that part but not the jaw i also feel like my chin is too small please any advice is much appreciated
