Sam's question (2)

I've been sucking my thumb till I was 10 and that caused me to have a recessed chin like it's bad bad does anyone have any experience on how to fix it like I want forward growth so bad I can't even go outside without physically being disgusted by myself

This is a bit random but growing up in was never taught how to but I have stawberry legs and ingrown hair and it's always dry how do people make their legs all nice and shiny and smooth?
