If in later life she has mastered her hunger drive by ego control, she may assume that she can control her fate herself. But that ego may in fact be very weak, because it has been built by cutting herself off from the mainstream of life through severe dieting. It is built on negative rather than positive need. In a real life crisis, such an ego may fail to operate because she does not know consciously what her own needs are.

Only when her ego is firmly rooted in her own feminine feeling can a woman be released from her compulsive behavior.
