Send better pictures if you want us to assess your case properly. Look up "Frankfort Horizontal Plane" and pose accordingly. Set your phone ~2 meters / 7 feet away from your face. Do no jutt your jaw, do not tense up your facial/neck muscles, keep your whole face as neutral as possible.

That's cool, more power to you. However, you have to understand that fixing only one isolated feature might not be enough to generate a significant improvement in facial harmony. Most facial features interact with one another, so if you only fix one and not the other(s), you could be left with an underwhelming result.
It's not about developing more insecurities than you already have, but about understanding how facial aesthetics work.
For example, on a vertical axis, the chin is appraised proportionately to the philtrum (chin to philtrum ratio). Based on the photos you have provided, your philtrum is very long. As a consequence, if you alter the chin (genioplasty/implant), you should alter the philtrum as well (lip lift) to achieve proper harmony.
