A song!

Sometimes there is a song that you hear that brings you right back to somepoint in your life and reminds of those feelings that you had. I was reading tonight heard this song and really listened to the lyrics...I remember...

I wish you could see me now
I wish I could show you how
I'm not who i was
Used to be mad at you
A little on the hurt-side too
But i'm not who I was
I Found my way around
To foriving you, sometime ago
But I never got to tell you
So..
I found us in a photograph
Saw me and I had to laugh
You know, I'm not who I was
Ooo, there you were right above me
And I wonder if you ever loved me
Just for who i was
When the pain came back again
Like a bitter friend
It was all that I could do
To keep myself from blaming you
Ooo.
I reckon it's a funny thing
Figured out I can sing
Now I'm not who i was
I write about love and such
Maybe because I want it so much
I'm not who i was
I was thinkin' maybe I,
I Should let you know
That I am not the same
But I never did forget your name
Hello
Ooo, a-nah-nah-nah-nah-nah-nah-nah-nah-nah-nah
But the thing that I find most amazing,
In amazing grace
Is the chance to give it out
Maybe that's what love is all about
I wish you could see me now
I wish I could show you how
I'm not who i was

Well then...who am I now? Who do I want to be? What do I want to show? But in all truth...who am I?
