I recently graduated from Carlbrook. I don't know when you went there cooltherapy but I can assure you that there was no underground going on. Everything was controlled. I heard that there was an underground in Carlbrook history but they did away with it by creating suspension and action plans as opposed to just programs. However, over the last couple years, suspension was turned into "a necessary part of everyone's treatment" as oppposed to just a punishment. I admit, there were things that happened during my stay which were to say the least, out of the ordinary. Nevertheless, the school quickly discovered it and the people were immediatley punished. They even contained it so much that no one on campus, besides for the people that were involved in it, ever knew what really happened.
I graduated last August and since I've been gone, I've noticed a lot of similar feelings on the internet that I'm feeling right now. I was pretty sure I loved Carlbrook after I graduated, but now, I'm beginning to question their methods. But of course, I can't tell anyone this because then my friends will hate me.
