It is so hard to catch a falling star

Why can I still believe in tomorrow,
When all I have tried was just in vain
Is it worth the fight I couldn't start believing that those feelings who died could face the pain
I don't need no diamond rings, alibis no more.
Who do you think you are?
Cause once again you broke my heart
I know that love went just too far
Its hard to catch a falling star
But now I finally realize, you're a brown eyed angel in disguise
Just one step too far so tell me honestly
Who do you think you are ?
