Sweetness777, no one can answer this question without adequate photos at least and of course at best an exam. You would probably benefit from either a chin implant or a chin shave; obviously an exam would be needed to tell you which. See an experienced surgeon that does "only faces" and has a lot of good photos to peruse. Search the Internet. Good luck!
The decision to perform a chin implant is made at rest, not upon animation. If there is pointy chin at rest with adequate projection, a Silastic pre-jowl implant can be inesrted to give only added width to the pointy chin. For more information, diagrams of the implants along with many examples, please see the video and the link below
