Took me on a limb
You've taken everything
Everything
As the clouds come in
As the rain begins
Rain begins
Heroin
Heroin
I'm out of it
No more songs to sing
No more love to bring
Love to bring
As the rain begins
Such a silly thing
Heroin
Heroin
Heroin
I'm out of it
La la la la la la la la la la
La la la la la la la la la la
Heroin
Heroin
I'm out of it
You've taken everything
Everything
As the clouds come in
As the rain begins
Rain begins
Heroin
I'm out of it
No more love to bring
Love to bring
As the rain begins
Such a silly thing
Heroin
Heroin
I'm out of it
La la la la la la la la la la
Heroin
I'm out of it
I think it's pretty self explanatory; he's hooked on smack and it's ruining his life ("you've taken everything"). He can't sustain a relationship or anything, and all happiness is gone.
