Kristen's secret:Sexual abuse by trusted teachers - coverup by administration

CBS News   Tormented by horrific memories of being sexually abused years before by a middle school gym teacher, Kristen Cunnane thought about killing herself -- but then she decided to fight back

[....] At the age of 32, Kristen seems to have life licked. But look closer and there is darkness around her, a residue of painful memories that were long buried.

It was 2010 when Kristen began having disturbing flashbacks.

"When I first started going through the flashbacks and remembering everything that had happened to me, I didn't wanna live anymore," she said. "It was like I could see the stuff that had happened to me happening again ... stuff that I had been able to completely black out for more than 10 years."

Back in the mid-1990s, Kristen was a student there and her favorite teacher was Julie Correa, who taught physical education and coached the girl's sports teams.[...]
