Being part of a high control group is similar to being institutionalised. You rely on someone else to make the important decisions in your life and tell you what to do and when. Everyone in your close circle believes the same as you and monitors you to make sure you conform. The conditioning runs so deep that it can manifest itself even when you have broken free from the organisation and no longer believe the doctrines and ideas.
It takes great courage to walk away from the organisation and the people you have known and trusted all your life. It is similar to a bereavement since you are cut off emotionally from many you love and respect in a very profound way. You have also lost the framework and ideology that shaped your life losing the Devine along with the physical relationships. Anger, depression and stress are natural reactions and in some ways are part of the recovery process.
Having had the courage to walk away from the lie is the first step, it is the first battle won and a good beginning but the final victory over the organisation can only come when your life is truly your own and you no longer liver in fear of their opinion and disapproval.
