Bipolar can be a pretty convenient tag at times. Sometimes we simply have a low tolerance for deep feeling, eccentric, or unique individuals. On the other hand, someone with true bipolar will often function in relationships and life better with proper treatment from drastic changes in diet to a more traditional approach. That is a personal journey. Do research from an impartial resource (not a drug manufacturing site!) and go from there.
As far as your CEDU experience is concerned, I think many people share your sense of social dislocation after attending the program. Years after CEDU, I was affected in the social realm in two ways. One, I distanced myself from people because friendship at CEDU consisted of bullying, humiliation, snitching, and exploiting your pain. On the other hand,CEDU placed us in a tightly controlled environment with highly contrived, intense peer experiences that cannot be duplicated on the outside. It would be easy to subconsciously feel that outside interactions were pale or shallow by comparison.
Unfortunately, leaving CEDU and knowing there was something very, very wrong about the place did not help me. I had no one who I could discuss it with who would understand, and because I split, I was completely cut off from peers inside. I really wasn't capable of making a mental appraisal of the situation to at least gain a cognitive awareness of why I felt so dislocated.
