why you had to go?

There is an question, in the corner of my mind. never asked you / why you had to go? Is there any answer ? So let me to know / I am here / waiting for you / My heart is burning / If you were here I wouldn't hesitate to smile/ If you were here I wouldn't cry/ If you were here I wouldn't ... But you are not here .../ It is all reality ...you are not here...
