Hey guys, im 22 male

Stumbling upon mewing a couple of weeks ago i've began to correct my tongue,head,neck, spine posture.

The problem is that my maxilla is heavily recessed, evidence that suggest that genetically that isnt the case is that i have a (dark eye circles, horizontal stretch mark on my nose(crooked nose btw), space from my upper lip and front incisors, my neck posture of most of my life was in a lordosis position (no one told me how to hold my head + gaming(24/7 literally). My last 2  molars are slanted laterally indicating that my maxilla fell down.

As i've fixed my posture my mandible(lower teeth) goes forward and protrudes over my maxilla(upper teeth). Getting to this phase i've experienced some resistance cuz of mine muscles and ligaments getting used to the new position.

TL;DR is it possible to reverse the negative changes if the original mould was good i.e upswing the maxilla forward and upwards
