What Did I Do?

I can feel my heart beating
I can feel the pulsing blood
yet I can feel nothing
since you left

Life isn't worth living
I should just stop breathing
If every minute
Of every day
I don't have you

Why can't I forget you?
Why can't you leave?
You make me hurt
You make me cry
But you make me love you with one small smile

Things are worse
I can't sleep
I can't eat
You have taken all of my energy
This leaves me with one question

What did I do?
