Having chin/jawline surgery tomorrow I'm super scared because it's only local anesthesia. How bad is the pain, really??

I'm terrified of my chin and jaw line liposuction tomorrow. I'm to the point I want to cancel and forfeit my depost. I can't believe this will be done with local anesthesia. How bad do your patients say the pain is post op? Are you patients fully awake while getting the surgery? I was told I'd get xanax but that won't make me pass out. Do some patients actually fall asleep??? THANK YOU Scared to death in fl.
