The women I know who have had abortions have this on their mind nearly all the time, even 10-15 years after. Some of them have some really shocking dreams. They are frequently along the line of: they are on a playground, or a park, or some other pleasant place. The child that they aborted is there, at the age they would have been had they not been killed. The child always has a name and calls the mother "mom" or "mommy". There is always a clear picture of what the child looks like. The child in the dream will take their mother's hand and ask why they were aborted - after the mother gives her explanation, the child might say that they forgive their mother.
Pretty hard to have recurring dreams like that and not be affected. I would think that those without a strong faith in God would have difficulty in dealing with such dreams - thus the higher suicide rate.
