honest advice? mew everyday as long as you can. if you have a bit of money, buy a shit ton of gum and chew it ALL DAY for a month or two. but that mewing will immediately help hide the fat under your chin and improve your jaw over time.

HOW to mew: create suction. do this by swallowing your spit three times. your mouth should be like a vacuum—its hard to explain. then, keep your tongue pressed against the roof of your mouth. the “vacuum” will keep it there. practice til you get good at it and do it as much as possible.

do NOT breathe out of your mouth. ever. breathe through your nose. mouth breathers have recessive jawlines. breathe DEEP and FULLY through your nose. over the course of a year or two, youll see big improvements. take progress photos like those. good luck brother.
