Describe symbolism in Kissing Doorknobs by Terry Spencer Hesser

In Chapter One, Tara Sullivan is having a hard time with voices in her head. She sounds sweet and funny, with a dry sense of humor and a self-deprecating way of putting things. In a voice that sounds much like a child's voice, Hesser has created a character who symbolizes her fears from the inside, allowing the reader to experience Tara's confusion and frustration in the terms she herself uses.
