I strongly dislike my braces

I'm rather fed up of braces at the moment. They have been cutting up my lip for the last week and it hurts and I'm fed up. Usually the sore bit of lip or cheek toughens up after a couple of days and some wax on the offending braces.
Not this time! No, my braces are currently working their way through the mountain of wax I have applied and continuing through my lip.
They just won't stop!
Why can't braces have rounded corners, it would stop all this annoyance and pain.
