Can't let u go

I'm trying my best,
But I can't
I'm giving every breathe I have
And yet I can't manage to let you go
I can't let go my world
I can't let go my love
I can't let go a drop of my blood
I can't take this risk,
I don't want to suffer
I don't want to feel pain from one time to another.
I love you from all my heart
And my love is demonstrated by every pound
But still I have to go,
For a reason I don't dare to know,
But deep inside I know that I can't go on without you.
