Follow-up: Is this short face syndrome or weak chin and jaw? Zero upper teeth show

WONDERING if I've got short face syndrome or a combo of things like weak chin/jaw, odd lips (unsure how to describe??). I DO have a large nose, weak chin, deep bite, no upper teeth show. I don't want further pain or clenched teeth (something I do 24/7 unless I think about it) and REALLY don't want to wear down my good teeth or get sleep apnea like mom. Yes, I'd like a nicer face but more, am just unsure what's going on. I don't know ANYONE who doesn't show upper teeth except sister.
