What Am I Supposed To Do?

From the moment you left my life forever
Tears never ceased to fall
I no longer woke up smiling
And I feel like I've lost it all
The second you said good bye for good
My heart tightened inside my chest
I no longer felt like dreaming
There was no more moment of rest
The very first breath without your scent
And I felt like my lungs were giving in
I no longer wanted to smell the flowers
Every time I breathe, I think I'm committing a sin
You left so fast, I almost didn't see you go
Your shadow almost couldn't keep up with you
I loved you more than life itself
So now exactly what am I supposed to do?
