What Happens When?

Ok so
What happens when you can't fight the urge
I try my hardest to stay strong for you
You know I would die for you
But what happens when I can't fight the urge
And that blade looks so tempting
And I just wanna feel the blood run out
With nothing left but a lifeless corpse
That was once I
But no
Whenever I talk to you
You tell me how scared you are
And that you need me here
How can I deny you?
If I really am the reason your fighting
So what happens when
I lose the person I love
And I can no longer fight the urge
This pain is so strong
And it tears me apart
Knowing that if I left now
You would be hurt
And you would give up
Which you know I'm against
I love you so much
So take no offense
To what I'm about to say babe
Just know in my heart
I am yours
And shall always be
You know that with those three little words
That you speak so softly
So gentle
That you can keep me here just one moment longer
You're the reason I fight the urge
So what happens when
I can fight it no longer?
