Hi, I'm Amanda And I'm Very Young ,and Unconfident About

Hi, I'm Amanda and i'm very young ,and unconfident about my height. I am 5'8 and I would like to lose about three inches off of my height. I have tried drinking coffee, curling up in a ball when I sleep, slouching, basically everything. I have also been trying to find a website that does height reduction surgery, so you can tell i'm very serious about trying to get smaller. Is there ANY possible way I can reduce my height?
