I feel so depressed with my height?

well it seems that my life is ruined. i am 5 foot 6 and i hate it, its to tall for me i hate being tall its just indescribable in words to tell you how i feel about this stupid tall lanky body of mine. i go to the store i have this slouch on my back and i look so silly like that why i do that is because im trying to act shorter than my height. sigh..... i just wish i was about 4 foot 9 or 10 oooo i could see self at that height i could live my life so good act more enthusiasticly and be happy and peppy all the time i could live my life to the fullest if i were 4 foot 9 or 10 man you dont know how i feel. i cant even where my favorite shoes because they have a heel and make me taller i dont want to be taller i want to be short. is that to much to ask. i know i put a lot of pressure on just somthing as simple as height but thats how much i care about it and i know there are people out there just like me. i know how to get to 4 foot 9 or 10 simply i have to limit all the tdifferent ypes of cells in my body that are made proportionaly that takes place in the genes because genes tell the cell what to do i have to locate the genes that are responsible for cell growth and or divison for all the different types of cells in my body for all the cells in my entire body. i know it sounds pretty tough but its possible i mean our technology advancing has to start in some point of time. i have a good plan and i know it works but ive got to find a way how to act upon it. please excuse my misspelling for i am typing very fast. thankyou and respond respectfully on how this sounds.
