I don't understand

 How does your life go on when someone that you love is gone?                                                            I don't understand                                                                  

How do I face the endless nights?  When all I do is cry.                                                                      I don't understand.                                                                      

I hear them say it will take time, But they don't see me all the time.                            

 I hear them say you'll make it through.  I hope and pray I really do.                              Nothing really matters now, cause missing you is all I do.                                                                    I don't understand.                                                                  

All these changes here within.  Do there best to do me in.                                                                   I don't understand.                                                            

I hear them say a better place, but I don't look them in the face.                                      I hear them say no more pain,  but all there words are all in vain.                                  How does a tiny sparrow fly across the stormey winter sky??                                                               I don't understand.                                                                  

How does this fragile heart inside find a way to say good-bye?                                                              I don't understand.
