Thank you for sharing that story.
"Advice for those clinging to their captors" may have worked as a title, too.
We need to bear in mind, though, that not everyone has such extreme circumstances. Some people have healthy relationships with their parents, they just don't talk much about religion and deflect any attempts at guilt or emotional pleas to return. (Or they just go to occasional meetings and 1 hour in a month field circus, and then go home and live peaceful lives with friends and family they have known for many years).
If you are under duress from abusive family members under the spell of the Org, get out from under their control ASAP. Otherwise you're going to spend your years in misery trying to placate people who don't know how to love you...
Amen to that.
On the other hand, I wonder if you would have spent your life at least partially under the mental control of the Borg, if not for your mother's abusive behaviour? If you had stayed at home, might you have got baptised at a later age due to peer pressure?
I know it may sound strange, but if you can find some small thing to be grateful to her for, like being a part of your independence and freedom from this cult, it may help you to not hate her. She will likely go to her grave miserable, you will not. Pity her, if possible.
At seventeen I left to join the military in order to get away from her and her toxic JW environment.
Early exposure to life in the real world no doubt served you well.
