She feels alone with her feelings. This is just the same with rape survivors. She feels cheated - her trust has been betrayed. Survivors feel that they should be coping better. Their anger turns inward and can result in PPD, anxiety attacks, post traumatic stress disorder, etc.
Women often conform to the system - they feel bound to follow the male system.
Postpartum depression is the grief that follows the helplessness in the face of male violence. We need to set up a system which is separate from the medical system. We must support each other, question obstetric policies and practises, and get involved in the politics of birth. We must help the woman to process her experience and make it whole for her by using active listening. A woman needs to feel validated, to know she is believed, and to help herself feel she can find the strength within herself to cope - to regain control.
