You tell me it gets better, it gets better in time

You say I'll pull myself together, pull it together
You'll be fine
Tell me,  what the hell do you know? 
What do you know?
Tell me how the hell could you know
How could you know

Till it happens to you, you don't know
How it feels
Till it happens to you, you won't know
It won't be real
Till your world burns and crashes
Till you're at the end, the end of your rope
Till you're standing in my shoes, I don't wanna hear nothing from you
From you, from you, 'cause you don't know                         
     

     Til it happens to you, you won't know how I feel.
