18 years old, 115 lbs 28F to a more manageable size

My chest has always been bigger than everybody else’s even though I was often the shorter and smallest in my class. In the last four years, my chest size has reached a new level. It gives me frequent back pain, gives me awful posture, and low self-esteem. I often feel like I can’t wear anything or look nice because of how I feel about myself. Additionally in the last three years I’ve developed the habit of always wearing a sweatshirt of jacket to hide my chest and make it look smaller as well. I almost never go out without something else over my chest. I’ve been thinking about this for years and my parents have been considering be idea as well. I just made a consultation for October, so I’ll keep y’all updated! My plan is to hopefully have the surgery done in late May: early June, so I can heal before I start college in the fall. I’ll let y’all know how it goes!!
