About to go have gallbladder surgery, i'm very scared that i won't wake up from antistetics or go into shock when cut, am i overreacting? i'm healthy

Yes, very safe: Cholecystectomy can be done open or laparoscopically (most common). The risks include: internal bleeding, injury to the bile ducts, injury to the small intestine by one of the instruments used during surgery and the general risks of anesthesia. The overall risks are very small, less than 1% in total. Go to: https://www.facs.org/~/media/files/education/patient%20ed/cholesys.ashx
