Do I have a weak chin? Do I need jaw surgery? (Photos)

When I was younger I had a pretty strong cleft chin, but you can't really see it now. When I got my braces off last year I was told I may need jaw surgery. I think it's that serious of a case. I don't think my chin super weak either. I think my lower stopped growing or is growing slower than my upper one. Oh I'm 19 btw. (Also not my real location)
