a shadow of (one's) former self
A person whose personality has changed dramatically to become decreased in vivacity in some way, often following some traumatic event. Ever since Tim was in that accident, he's been a shadow of his former self. She's so quiet now, like a shadow of her former self. Does anyone know what happened to the bubbly girl we once knew?
