How do you manage your double chin?

Maybe it's because I got my forward head posture corrected, but even though I already had a lot of fat on my face, my double chin has gotten really bad. Even though I have an average build, I'm really worried because just looking at my chin makes me look obese. I haven't been practicing Gua Sha consistently, and I tried following along with Trudi on YouTube—I can't quite remember the name—and while the results seemed okay, the back of my head felt so tight that it gave me a headache. There are so many good procedures out there; would a procedure really be the best option?
