Breast reduction surgery

Has anyone on here had a breast reduction surgery? Im a 44H and I want to go down to a C or a D. and i have a consultation with the surgeon on the 6th, but ive never had any sort of surgery and I have really bad anxiety. I know I definitely want to get the surgery, ive been for sure on the surgery since i was like 13. I just have anxiety about blood and needles and catheters. What is your experience with the surgery, anything I should know and what I can do to help ease my anxiety?
