This is my first, so there can be some mistakes, but it sounds about right to me

It’s my first summer since you told me that we're over
It’s my first summer since you went away
But don’t go thinking there’s a chip upon my shoulder
Cos I assure you everythings OK
As I'm sittin’ on top of the world

Cos I’m just going crazy
I’m just climbing up the wall
I just cry myself to sleep at night
wondering why you never call
You were only all I dreamed of
and the only one I want
So why should I feel bad about it
no it hardly hurts at all

Each time I see you I get shivers
and my hand shake
And everytime I feel like such a fool
But don’t you worry if I stumble and
my voice breaks
Cos I assure you everything is cool
as I’m sittin’ on top of the world

Cos I’m just going crazy
I’m just climbing up the wall
I just cry myself to sleep at night
wondering why you never call
You were only all I dreamed of
and the only one I want
So why should I feel bad about it
no it hardly hurts at all

Maybe someday you will know what i mean
Yeah, you may even fall apart
Maybe you’ll know how it feels when
someone tears it apart, apart

I’m just going crazy
I’m just climbing up the wall
I just cry myself to sleep at night
‘wondering why you never call
You were only all I dreamed of
and the only one I want
So why should i feel bad about it
no it hardly hurts at al
