Why does it look like I have such a long chin now and what can I do about it? (photo)

I used to have a smaller, much cuter chin. Now it looks so long and big, especially when I smile. If you look at my profile pic from over 20 years ago, you'll see how small my chin is. I didn't gain weight so it's not a double chin. As a matter of fact I think my face is too thin. What can I do to get my chin back?
