1. Sadly, I now have a mother who outright told me that if I dissociated, she would have to remain loyal to Jehovah and shun me.
2. Unfortunately, if you want to find real psychological and sociological scientific literature, you won't find it by searching for "cults."

"Dependence on a leader
Cult leaders demand loyalty and suppress criticism. For them, power must be absolute. Authoritarianism takes precedence over anything else. They often claim that 'special' knowledge, secret ancient doctrines or divine revelation is guiding them.
But cults, because they only serve the leader, exploit and pervert that useful habit and, to establish and maintain itself, does everything possible to destroy family ties, and any other secure and conventional anchor in a person's life. This has the effect of strengthening a member's bond with the cult and its leader. From this viewpoint, the cults that promote celibacy and the cults that encourage indulgence in sexual promiscuity are seeking the same ends — the destruction of normal family life and the substitution of dependence on the cult group authority."
