The suffering caused by abortion can be about many different feelings, such as anger, grief, guilt, shame, and spiritual injury.
Difficult feelings may not present themselves clearly and directly. A woman may find herself feeling restless or agitated and having difficulty sleeping, but not have any idea what is troubling her. She might, in fact, be developing serious depression.
It may be very clear to you which feeling you've been struggling with and why. Or you may feel confused because it sounds like several feelings are troubling you. However your post-abortion distress has manifested itself, understanding your feelings are the first step to healing.
For a deeper look into these feelings you can order the book, Peace After Abortion.
