Do you realize your size? Like height weight etc

Im abnormally tall and i dont realize it till i see others my height then i understand why people back up when they see me. Ill be honest though it kinda makes me feel like a freak of nature. Im tall and move fast so i can kinda understand why it may startle people but still...Being introverted and tall is a curse we want to blend in but kinda hard with someone like me.
