What should you say if someone asks your name but you HATE it and feel like isn't yours?

first of all..a big LOL because you make your own name sound funny yourself...but really, when i read your problem i kinda scanned through what you wrote because i dont really like reading long things and then i got a glimpse that you hate your name...well how bout you a) change your name legally b) self promote a nick name to everyone you know c) become an anti-social so's no one will ask you name "be invisible".....i think you should go for a)
