i am a 25 year old guy who is really really short for his age. I am just 5 feet though i try my best to shrug this off and lead a normal life , people around me ,my friends,Relatives and People i love ...
Our society is not perfect , one reason is the way we treat the different. Some times people can be real cruel without even noticing. It takes time for people to understand what they are doing and grow up a little. When you become speechless they realse it bothers you and it just keeps them going. I think you need to use humor in your case. when people make a joke about you join them , it might be hard at the begining but as time passes by you will overcome it. Try making your short apperance your advantage.. say something like "the things you can seee from here"..
I feel for you it is not easy but if the people surrounding you won't stop maybe they are not truly your friends. did you ever tell them it bothers you?
Good Luck.
