"Estoy Aquí" by Shakira is a song that speaks of the sadness of a person who knows that their love will not return. She knows that time cannot change what happened, but still, she continues to wait. She tries to forget him, but she cannot, and she feels crazy trying to change her past. She continues to wait for her love to return, even though she knows that a thousand years would not be enough for him to forgive her.
