How do I fix my face? Please help

Ok here is PROOF that I used to have a killer side profile. My jawline was great, I loved my jawline.

BUT NOW, I look like this....

How do I get rid of that excess weight? I’m not fat, I’m only 115 lbs (on a 5”1 petite frame) I’m not even sure where the weight is exactly because from the front angle I look fine. But my side profile is just bleh and I’m super self conscious because it does show up in pictures sometimes and I just really miss my old face! lol

Here’s how I look NOW...

Here’s how I used to look a few years ago

And here’s the current front angle
