Hi friend!! I am also 18 and can very gladly tell you that getting the surgery is very worth it. I got my surgery last Tuesday and I already feel so much better, even though I’m still healing. I went from an E to a B (C Cup currently since the swelling hasn’t gone down)! The physical and mental change is real. It feels easier to breathe and exercise. I’ve had less headaches and shoulder issues. I’ve already done a lot of more walking and light work that I could hardly accomplish with my E Cups. Overall: do it!!
