'That one'

Yeah, i agree ,am getting focussed on one and only one.My mood swings up and low depending on that one.If that one is with me ,am the happiest,i become the princess of this world.If that one is far,am the saddest,i become the 'damsel in distress'kinda girl.I learn to live seeing that one,nope am wrong.I live for that one,this is the right note.Well,where have been that one all these years?How did i live then?i dont know...

That one is my passion,my bliss,my wish,my quest,my identity,my life.

Guess,u understood what is 'that one'.
