I finally have a date in the books for top surgery but now I’m getting cold feet. I’ve been thinking about this surgery & binding on and off for 9 years, but now that we’re SO close I’m like “what if I just want a reduction? What if I want to have Some boob? What if I just want to find The Right Bra” bc I think boobs are GREAT and THEN there’s the more serious concern that when my heavy chest is gone, there will be nothing to distract me from my hips, my ass, my stomach which for years all felt way too big. What if getting rid of the volume at the top of my torso makes the volume at the bottom so much more pronounced (I’ll go from being a rectangle when binding to being a triangle) This feels like fucked up feelings to have but I’m so scared of reverting back to a time where I more actively hated my body
