Who am I, who am I, who am I, who am I without you?

I thought I knew all the answers to what it's all about
I never once had to think about what I'd do without
The kind of lovin' you gave me, but now you let me down
I wasn't ready to let it go, but I'm over that now

I was always the easy-come with the easy-go
Facing the future without you, well, that ain't easy, no
The person I am alone is somebody I don't know
I wanna be holding on to you, but you let me go

Why did I do this to myself?
Why did I do this to myself?
Why did I do this to myself?

Now I'm having an identity crisis
And you know that I don't ever get like this
The adrenaline is doing my mind in
You're my medicine, but now I can't find it
So I'm having an identity crisis
And I'm doing all I can just to fight it
But my head is spinning, I can't define it
I can't hide it, no, I can't hide it
That I'm having an identity crisis

How did I go from the top of the world to underground?
What do I do to get movin' and say I'm better now?
The hardest part is to start it up without knowing how
I can't deny it, I lied when I said I'm over that now

Why did I do this to myself?
Why did I do this to myself?
Why did I do this to myself?

Now I'm having an identity crisis
And you know that I don't ever get like this
The adrenaline is doing my mind in
You're my medicine, but now I can't find it
So I'm having an identity crisis
And I'm doing all I can just to fight it
But my head is spinning, I can't define it
I can't hide it, no, I can't hide it
That I'm having an identity crisis
