I let myself believe
Your cycle of promises bruisin' my confidence
You told me I was crazy
But manipulation is your middle name, and you
Thought that I'd leave with a kiss
But I saw you burning that bridge
And I'm walking right over it
They say that karma's a bitch
And now I know all of your tricks
Better sleep with one eye open
'Cause I'm a psycho, you made me like this, you gon' regret
That now I'm ice-cold, you stole my heart, so what'd you expect?
I'm comin', you're runnin' away, I've got all day
And I won't stop until you're psycho
I'll do what you did, that's my revenge, oh-oh, oh
Oh-oh-oh-oh-oh, oh, oh-oh-oh-oh-oh, oh
Oh-oh-oh-oh-oh, whoa, oh-oh, oh, oh-oh, oh
You always took advantage
Of my generosity, used it against me
But I'm all out of givin' a shit
And you're gonna wish you were dead, but keep wishin' 'cause
They say that karma's a bitch
And now I know all of your tricks
Better sleep with one eye open
'Cause I'm a psycho, you made me like this, you gon' regret
That now I'm ice-cold, you stole my heart, so what'd you expect?
I'm comin', you're runnin' away, I've got all day
And I won't stop until you're psycho
I'll do what you did, that's my revenge, oh-oh, oh
Oh-oh-oh-oh-oh, oh, oh-oh-oh-oh-oh, oh ('cause I'm a psycho)
Oh-oh-oh-oh-oh, whoa, oh-oh, oh, oh-oh, oh (I'll make you psycho)
Oh-oh-oh-oh-oh, oh, oh-oh-oh-oh-oh, oh
Oh-oh-oh-oh-oh, whoa, oh-oh, oh, oh-oh, oh
'Cause I'm a psycho, you made me like this, you gon' regret
That now I'm ice-cold, you stole my heart, so what'd you expect?
I'm comin', you're runnin' away, I've got all day
And I won't stop until you're psycho
I'll do what you did, that's my revenge
Oh-oh-oh-oh-oh, oh, oh-oh-oh-oh-oh, oh ('cause I'm a psycho)
Oh-oh-oh-oh-oh, whoa, oh-oh, oh, oh-oh, oh (I'll make you psycho)
Oh-oh-oh-oh-oh, oh, oh-oh-oh-oh-oh, oh
And I won't stop until you're psycho
I'll do what you did, that's my revenge
