okay so i'm currently in the middle of a talent competition and i sang halleluja. the judges told me i had great vocals but...lacked emotion

he said pull emotion from the saddest point of my life and use it for my song. so i was thinking of singing vision of love by mariah carey

. the thing is...im not exactly sure what kind of emotion or mood to put into that song. any ideas would be GREATLY APPRECIATED!!!!!! thank you in advance!
