If It Dosnt Kill You Does It Make You Stronger?

I know a girl.
She means the entire world to me.
Everyday shes faced with people screaming.
I know that her tears are streaming.
I know what is behind the smile.
The cracking fading girl.
I've never been so honoured to be able to call her my friend.
I would run for her untill the sun sets.
It absaloutly kills me to know she's dieing inside.
All I can do is hope I can be her light.
She's so strong.
Yet I know what she hides.
I can't stand to be on the phone and just listen to her cry.
She not just a friend anymore.
She so so much more.
She's a sister thats been through it all.
Helped me in my darkest time.
So now it is MY turn.
And I will NEVER Leave her side!
