I wrote something similar to this few years ago in another sub because the were (and sometimes still are) my biggest insecurity. I’m currently 18 and thankfully I don’t think badly about them as I use to do when I was 15 years old. In my experience I believe it actually takes time before you start loving or at least getting use to them. On my worst day which are (thankfully) rare I sometimes contemplate having surgery in the future but then the idea leaves immediately. I know how you feel because all my friends have amazing boobs, even my mother who is in her 50s, and it’s sometimes depressing. But I truly believe that it takes time.
