I might smile or I might cry
Might tell the truth or I might lie
Lot of what I do, girl - I'm quite wild
I'm just trying to move along my lifelines
And make me greater
That's me, just a little unstable

I'm usually sane
Normal on every way
But someone flicked the switch
Now I've got this nervous twitch
I'm shakin' like a leaf
You have infected me
No inhibitions
They're all gone
Split personality
It won't be long
Before I lose my mind
I'm unstable

Who ooh ohh
I'm so crazy
Who ooh ooh
'Bout ya lately
Ironic I know
I got it to go
Who ooh ooh
I'm unstable

I used to be real calm
Like a ballerina girl
Straight A student chick
Until you came and rocked my world
I'm certified for sure
You're the drug
I'm craving more
No intermission
This is the show
If you figure me out
Let me know
Before I lose my mind
I'm unstable

Who ooh ohh
I'm so crazy
Who ooh ooh
'Bout ya lately
Ironic I know
I got it to go
Who ooh ooh
I'm unstable

I guess I'm crazy
A little unstable maybe
S*** whatever God made me
F*** what they say
If you wanna go wild
Go ahead, don't axe nobody, girl
I got a split personality
My sixth sense silently
Seems to contradict my reality
The twitches in my lip
Keep reminding me that something ain't right
But no matter we see monkeys tonight

No inhibitions
They're all gone
Split personality
Won't be long
Before I love my mind
I'm unstable
Who ooh ohh
I'm so crazy
Who ooh ooh
'Bout ya lately
Ironic I know
I got it to go
Who ooh ooh
I'm unstable
