Someone I knew was forced to go to a 'conversion therapy' camp when they were 16 by their parents. It was a religious oriented one. (That was about 20 years go now, and it was south carolina, so I am wondering if it was this one or not)
She was in camp with 12 other people. They used aversion therapy, shock therapy, baptismal font to pray the gay away (immersion into cold water underwater until almost drowned) . When she was living with me at about 3 or 4 years ago, one of the people that went there died of an OD. At that point, out of the 13 folks that went to that session, 7 were dead. There were 5 over doeses, and 2 suicides. I know for many years she was highly suicidal... although she recovered and now is leading a productive life.
One thing the camp did not do is change her orientation. She's still as gay as ever, and flaming at that.
