How can i add demension to my flat-face?

i'm asian, so that's one of the reasons why my face is flat. i've been having PMJ disorder for more than an year now, and that deforms my face structure. i can't meet with the orthodontist until i'm finished with my teeth. my side face looks all drooped and i look like a pug. my front face is okay. if you gotta know in order to give me an answer, i'm 15 years old. i'm having a pretty hard time dealing with the condition my face is in right now, so any tips or advice?
