Cover art for Katie lyrics by Missy Higgins

This song really makes sense to me... It fits my life actually.

To me it means that there was a young girl who'd been hurt or abused (mentally or physically) but she never showed how sad she was. She faked happiness and showed a different face to everyone... a strong one, pretending that she could handle life. But then she found something she could control. Food. This control was seen by her as her only bit of freedom. She refused the help and felt alive, although she was still dying inside. In the end I believe Katie took her own life either by refusing the help and starving, or taking her life by pills because the wait for starvation was too long.
