Ama I candidate for a sliding genioplasty? (photo)

I have always been self conscious about my chin, it's always made my face look longer and it looks recessed from the side. I got chin filler a while ago but it made my face look a bit longer and instead of accentuating it, it made my chin look like it has more chin fat. I can't really close my mouth all the way without it being uncomfortable, and my jaw feels heavy a lot of the time. I'm used to it but I'd like to feel comfortable with my face/jaw. I was recommended a sliding genioplasty.
