The False Memory Syndrome Foundation compiles stories from "retractors"--men and women who came to believe in therapy that they had been horrifically abused as children, and who later concluded that these memories of horrific abuse were false.
There was a trend in the 80s for therapists to suspect that patients who presented with fairly severe emotional issues were suffering from traumatic episodes in their past, which they might not yet remember.
One woman who retracted her story eventually realized that many of her symptoms were indeed related to a traumatic event, and that this event was an abortion, not sexual abuse at the hands of her mother:
"By falsely accusing my mother of sexual abuse, I tapped into a dark pit of rage against her; rage that had been repressed for more than 30 years. An only child, I grew up under the thumb of authoritarian parents who pushed me to be the perfect daughter. Negative emotions were squelched, painful issues never discussed. Heading the list of taboo subjects was the stillbirth of a baby that happened when I was about four years old. Fifteen years later, that childhood event returned to haunt me. I got pregnant with my first serious boyfriend, and went through a hellish abortion. Even though I was living at home and going to university, I managed to keep the abortion secret from my parents. I tried to ignore my anguish, in vain, just as my parents had tried to ignore the stillbirth long ago. But my guilt, anger and misery festered. By the time I was 38, I was a walking time bomb. My therapist unwittingly lit the fuse."
