Somewhere I've left a little girl behind Building castles in the air I Look into the mirror and I get confused Cause someone else is there Who am I I'm changing so fast I hardly know Who I am I know I'm not the same as yesterday When my head was up in the clouds But the change has come just overnight Don't know yet just who I've found Who am I I'm changing so fast I hardly know Who I am Maybe it's just growing pains Cause I see myself somewhere Never want to lose what I started to be It'll be a while before I get there Somewhere I've left a little girl behind Building castles in the air I Look into the mirror and I get confused Cause someone else is there Who am I I'm changing so fast I hardly know Who I am
