What should I do to stop growing....?

Hi, I am 6 feet 6 inches tall and am growing unusually tall.I really have no problem with my height but it seems like everyone else does because they have to mention it. People are practically dissing me because of how tall I am. I really hate it when people say oh you are TALL. Anyway, I was told by one of my virtual friends from Yahoo Answers that hitting my head with a heavy object would help me to solve the problem for the long term. However, I couldn't find a heavy object so I hit my head hard on a metal bar instead and as a result I have a huge bump on the back of my head. What should I do now?
