I'm very insecure about the way my cheeks sag down and I have JOWLS but I'm only 21! The structure of my cheeks is very bad and I have no jawline. I have a slight overbite, I also have an issue with my jaw where it often 'clicks' and feels uncomfortable so I move it a lot. Do either of these have to do with it? Will fixing the overbite fix the problem? If not what do you recommend doing? I honestly know nothing about plastic surgery and this is my first time ever looking into it. Thanks.
