R5_rocks123 got it!!!!!! The answer is High School Musical!!!!!!!!
She lives in a shadow of a lonely girl
Voice so quiet you don't hear a word
Always talking but she can't be heard
You can see it there if you catch her eye
I know she's brave but she's trapped inside
Scared to talk but she don't know why
Wish I knew back then what I knew now
Wish I could somehow go back in time
And listen to my own advice
I'd tell her to speak up
Tell her to shout
Talk a bit louder
Be a bit prouder
Tell her she's beautiful
Wonderful
Everything she doesn't see
