Getting BBL without parents knowing - possibilities that an epidural can go wrong? What complications should I be aware of?

I’m 23yrs old 5.5 135lbs- getting BBL next Sat, I still live with my parents although I’m not planning to tell them I’m getting a bbl (there very strict and they think spending money on surgery is stupid ) I’m very scared about the surgery. My friend will also be getting hers done right after me - and will be spending 2 days at the hotel for recovery. I will be getting my arms.back.lovedhandles.and my abdomen- transfer to my butt (with epidural anesthesia) no sedation since I want to be awake
