3) The worst part of surgery is the fear and anxiety I felt leading up to it.
It's hard for me now, a month removed, to quantify exactly how scared I was before my surgery. But it goes without saying I have never been more anxious or more fearful of anything in my life. And now: nothing. No fear. No anxiety. When I said before mastectomies only remove breasts, I was only half truthful: they also remove the anxiety. Nothing about recovery -- not the soreness, not the painkiller-induced fog, not the emotional vulnerability -- is as difficult as living life under the crushing weight of fear and anxiety. I know it sounds simplistic, and this is a statement that can only be said with the benefit of hindsight, but here it is: surgery isn't so bad. The shit I put myself through before -- now that was torture.
