I agree that you look normal. I live in western europe and see many people around me with recessed jaws and little or no chin (including myself), it seems to be inherited. And I wonder, is there anything really wrong with this?
My jaw/chin is also a bit recessed but I think I won't correct it, I think it makes me 'me'.
Please now that the people in your daily life won't be focussed on your jaw, I am sure they just see a nice and beautiful guy.
But if it makes you so depressed, definitely go to see a good ortho and/ or surgeon, who can surely give you good advise about how to 'fix' this. I wish you very good luck!
