Requiring assistance in finding a song that does not show up on the internet.

For a while now I have been trying to find this song. My friend has been trying to find this song too. She's been trying to find it for years and nothing shows up. We listened to it a few times before. I have the lyrics accurate as well and still no results online...I've tried a lot of websites that find songs by typing in the lyrics. I typed them very accurate. I was wondering if someone out there in this community could seek the possible answers to a song that remains mysteriously hidden...

Here are some of the lyrics I remember from the song .

"Maybe I'm not so much better"
"I am me I'm proud to be me no one can get me down"
"You can call it vanity...cuz I am me"

How about more informations
gender of singer, music style, year ... all you know about the song.
title is probably "(cuz) i am me"
