[Refrain]
O-o-oh, was it all in my head?
O-o-oh, was it all in my head?

[Verse 1]
I must be crazy, insane, get way too carried away
There's something wrong with my brain, yeah, yeah
Been fantasizing and crying, been romanticizing
About all these boys who ain't never gon' like me

[Pre-Chorus]
I don't know why I thought it would be different this time
Thought you'd be the one but you're one of those guys
Can only blame myself, I made it up in my mind
In my mind

[Chorus]
When I call you don't pick up
Was it all in my head?
Shouldn't trust my gut
'Cause it was all in my head

[Refrain]
O-o-oh, was it all in my head?
O-o-oh, was it all in my head?
[Verse 2]
I feel so stupid, so used, so lost and confused
But I still want you, yeah, yeah
I should know better, it never turns to happy ever
After I know we won't end up together now

[Pre-Chorus]
I don't know why I thought it would be different this time
Thought you'd be the one but you're one of those guys
Can only blame myself, I made it up in my mind
In my mind

[Chorus]
When I call you don't pick up
Was it all in my head?
Shouldn't trust my gut
'Cause it was all in my head

[Refrain]
O-o-oh, was it all in my head?
O-o-oh, was it all in my head?

[Post-Chorus]
And I know, you don't love me at all
But I don't really want to move on
Think I made it up
Was it all in my head?
(O-o-oh, o-o-oh)
[Bridge]
I must be crazy, insane, get way too carried away
There's something wrong with my brain, yeah, yeah
Been fantasizing and crying, been romanticizing
About all these boys who ain't never gon' like me

[Refrain]
O-o-oh, was it all in my head?
O-o-oh, was it all in my head?

[Post-Chorus]
And I know, you don't love me at all
But I don't really want to move on
Think I made it up
Was it all in my head?
