Post-mandibular jowl concerns

I had jaw surgery in 2013.
 My malocclusion was so severe that I couldn't not get the surgery even though I didn't want to.
 At the time, I had it done at a hospital I knew, and
 I was also recommended a nose job, but I firmly refused because my purpose was medical treatment!
 Almost ten years have passed, and
 right after the surgery, the remaining flesh from the jawbone reduction
 looked like double chin fat.
 It's gotten worse and worse. I
 'm so stressed out that now I have a double chin even when I'm still
 . It's been a long time since I've seen my jawline. ㅎㅎ
 I take fewer pictures and my confidence is dropping.
 It seems like jaw lifting often doesn't work, and I heard
 that masseter muscle tying is a surgery that's only done to really old people in foreign countries.
 Should I just live like this? ㅎㅎㅎ I'm worried.
 What do you all think? 0
