LillyKane2005 got that one. It was Misery Business by Paramore. The next one is,

  I heard you're doing OK
But I want you to know
I'm addic-
I'm ________  to you
I can't pretend I don't care
When you don't think about me
Do you think I deserve this?

I tried to make you happy but you left anyway

I'm trying to forget that
I'm ________  to you
But I want it and I need it
I'm ________  to you
Now it's over
Can't forget what you said
And I never wanna do this again
