"And it's killin' me when you're away, I wanna leave and I wanna stay.
I'm so confused, So hard to choose.
Between the pleasure and the pain.
And I know it's wrong, and I know it's right.
Even if I try to win the fight, my heart would overrule my mind.
And I'm not strong enough to stay away"
(Apocalyptica - Not strong enough)

"And this kind of pain, only time takes away 
That's why it's harder to let you go 
And nothing I can do, without thinking of you 
That's why it's harder to let you go 
 
'Cause trying not to love you, only goes so far 
Trying not to need you, is tearing me apart"
(Nickelback - Trying not to love you)
