should i be focusing on fixing my posture or thumbpulling

[chiggaLTN]

14M, 15 in a week or 2.

was planning on getting marpe + facemask for my class 3 bite but realised that nhs ws never eva gonna fund it for free so i've basically accepted that that route is done for. rme is pure copium past 11.

i have very noticeable lordosis with my fat ass sticking out, and a severely recessed maxilla.
im an iqlet and can't be bothered to research what would be more beneficial for what. i've heard lots of ppl say that thumbpulling is cope but i really dgaf bcuz i need to keep coping bro. so anyways, main goal would be fixing recession. what should i focus on first or should i js do both at the same time.
im 5'11 rn so hopefully fixing apt can get me to 6'2 cuz im 90% sure that growth plates are closed.

stop the cope to start with. with your ass sticking out and bad posture try back extensions at the gym, neck curls and dead hangs those should all help with your posture. MARPE would defo help you icl go private ortho is my advice from someone who did it and it living in the uk as well, private ortho is more expensive but will give you the treatment needed for example i got a palette expander and other stuff for a crossbite

Posture yes, thumb pulling no. Go to an ortho to fix recessions.
