I regret having genioplasty and I want to reverse it. Will my soft tissue sag if I do it? (Photo)

I had my genioplasty 13 days ago and I hate the way my face looks now. My lower lip is smaller than it used to and my chin looks too long now. I know it’s still swollen but the more I see it the less I like it. Right now I can barely smile but I know that when I recover my smile it will look too long. I want to reverse it I am worried, what if my soft tissues never go back to normal and they become soggy since the Dr moved my chin 7mm. What are the dangers of a revision genioplasty so soon?
