Rushlow since when

Yeah, I'm doin' just fine, everything's goin' great
She's so out of my mind, totally erased
I've got it together
I'm better than I've ever been
Since when, why am I kidding myself?
From the moment she left, I've been over the edge
And I can't pull out of this spin
Well, I haven't been myself, since when
She used to believe, I was made to love her
And I, I can't even think of tryin' to love another
But maybe I've changed
I'm not the man I was then, yeah
Since when, who am I tryin' to fool
I can talk till I'm blue, I'm still over the edge
And I can't pull out of this spin
I haven't stopped thinkin' of her, since when
She used to be my whole world
My life revolved around hers
Maybe it could again
Maybe I'll get over this
Since when, why am I kidding myself?
From the moment she left, I've been over the edge
And I can't pull out of this spin
Well, I haven't been myself, since when
I can't quit thinking of her
I haven't been myself, since when
