Admittedly I'm tired and haven't read through all of this. However, one thing I'll add is that part of the con of any narcissistic cult is to seek out or create people that are codependent. You are too consumed with what their feelings and ripe for the picking. You are entitled to your own feelings and decisions, nothing about taking a stand for yourself is unhealthy, but they've got you all twisted up. That is the danger of a cult. Seeing that should terrify you on some level. They can and will get in your head. You need good boundaries that let you be you and them be them. Please leave them, take a stand for yourself, and perhaps see a counselor of some type.
Also, you are kind of a bad ass for seeing through the teachings. They are indeed negative, aimed at creating a divide between us and them. Eventually they'll get you to cheer on the genocide of the entire world by their god at Armageddon if they can.
Get out. Get healthy. Leave the toxic to their own toxic ideals and worry about you, not them.
