I just started mewing (dec 29/2018) and I discovered that my face is recessed. As a result, I can’t put the entirety of my back tongue on my soft pallete without suffocating. What do I prioritize? A constant pressure on other parts of the roof of my mouth or holding the tongue posture in the very back of my mouth for short periods of time? 

My tongue is also very large and I can’t fit the sides to touch the alveolar ridges. Once again, what do I prioritize? Do I have one side touch the alveolar ridges on it’s side  or should I flatten out my tongue So my mid tongue touches the ridges while the sides press against the molars?

Sorry for the long question, I’m just very insecure of how I look and I just want to be better looking and healthier.
