Bottom heavy round face on a thin young woman, what are my best options?

I've always had a very round face. As I've grown up I've thinned out in some areas but stayed full in others. The shape of my face really depresses me, I would feel so much prettier with a little more balance. I have TMJ and thus tried botox for the masseter muscles which did help some, but I still feel that there's a lot of excess heaviness from my mid cheek down. Considering buccal fat removal and possibly chin lipo, would that do anything to effect/define the jawline? Thanks! - 30 y/o female
