One of the things I had difficulty with when I realized that I needed to deal with my abortion was confession. I knew I needed to confess and wanted to do so, but found it extremely difficult to just walk into my nearest parish and say, "Bless me Father, it has been 20+ years since my last confession, and I killed my child." Rachel's Vineyard gave me the safe haven I needed to receive the healing I needed and to finally make that confession.
However for many women and men, they confess almost immediately upon realizing what they have done, but it doesn't "stick"; they feel the need to confess the abortion over and over again. The reason for this is that they can't forgive themselves. This is a key piece to the beginning of healing.
I came across this article on the Catholic Education Resource Center site. It is an article called An Imaginary Confession: The Aborted Child and Redemptive Love. It was written by Father Antoninus Wall, a Dominican priest. This imaginary confession takes place between the priest and a post abortive woman. The priest touches on many aspects of Catholic teaching on this topic as related to God's love and mercy, but also brings the woman's child into the equation explaining how the child is an intercessor and has sanctified the woman in her motherhood.

The other thing that I struggled with and still do to some extent is my role as a mother. While I do not have earthly children of my own, I am still a mother. Every post-abortive woman needs to at some point accept that role so as to begin and then continue her relationship with her child. I am firmly convinced that while God used one of my earthly friends to bring me back to my faith, it started 21 years ago with my daughters prayers.
