Broken heart

How can you mend a broken heart – Bee Gees

And how can you mend a broken heart? 
How can you stop the rain from falling down? 
How can you stop the sun from shining? 
What makes the world go round? 
How can you mend a this broken man? 
How can a loser ever win? 
Please help me mend my broken heart and let me live again.
