Mistaken lyrics

There's no joy without the pain
It's the pain that makes us strong
But sometimes it's just so hard to carry on
When you said that you don't care
When you say that you'll be there
Well, I wonder just how did things go so wrong
With everything we've had
(oh please tell me)
And you know it's just so sad
But who's to blame?

[chorus]:
(I was mistaken)
So who were you?
I thought I knew?
I guess I was mistaken
But I only wanted you
(I was mistaken)
So say goodbye
Don't tell me why
I guess I was mistaken
[ Lyrics from: http://www.lyricsmode.com/lyrics/s/save_ferris/mistaken.html ]
I know I can't run to you again
'cause' you would only run away
I guess there's nothing I can do to make you stay
You said that you would never leave
A lie you told and I believed
And now you want to go and throw this all away
So what is happening here?
(oh please tell me)
It's exactly as I feared
You're just the same, and

(repeat chorus)

As I blame myself again
Wondering what I did
You tell me that you still might care for me
You say you're just confused
But that's really no excuse
You don't get sympathy
'cause' I don't need this mindtrip,
I must be myself
Must free myself from you
And all you put me through

(repeat chorus)

'cause' I only wanted you
