Fixing a wide jaw and uneven chin? (Photo)

My face is very uneven because one side of my chin juts out further and my jaw is very shapeless and undefined as well as being too long and wide. Would it be possible to have it slimmed by having the skin somehow pulled closer to my jaw (it is currently very chubby) and having the bone shaved so it is smooth and even and more of that pointy heart shaped look or even just round?
