Depression After Rhinoplasty Surgery?

It took surgery for me to realize that my pre-surgery nose was unique and beautiful, and i realize now that body dysmorphic disorder probably lead me to get the nose surgery. Now that its done i realize that i loved my old nose, and am now extremely depressed that theres nothing i can do to bring it back. i currently hate my new, unnatural asymmetrical feeling/looking nose. How can i feel better about my decision, because i'm tired of the feelings of self loathing?
