Who am I?

Welcome to this whimsical tale of the JoyBirds and the FFFO's, the Fearful Formerly Fun One's is how their name actually goes. There's a song those JoyBirds have always sung that the FFFO's have always wanted gone. "When the BE and the WHO overtake the what and the do, That's when fear goes away, and you're free to say: I'll BE exactly WHO He made me to BE!" But the Formerly Fun One's preceded by Fear, successfully snuffed out their counterparts' attempts at cheer. They lost their BE, and their WHO was no more until Jeremiah had enough of their life of bore. Off to The Original, this JoyBird went to re-discover the life for which they were always meant!
