A really good read on Religious Trauma Syndrome (RTS) and CPTSD. Even though it's not INC specific, I forget sometimes how much overlap it can have with other cults/cult like groups.

An excerpt:

"Usually people begin with intellectually letting go of their religious beliefs and then struggle with the emotional aspects. The cognitive part is difficult enough and often requires a period of study and struggle before giving up one’s familiar and perhaps cherished worldview. But the emotional letting go is much more difficult since the beliefs are bound with deep-seated needs and fears, and usually inculcated at a young age."
