I wonder if it is less anger and more suffocating frustration.
I was angry and/or frustrated because I still believed in their opinions on morality, good, and bad. Christian morality only supports victimhood, self shame, and condemns everything normal for humans. For example, money is bad, sex is bad, self esteem is bad, being a doormat is good, blindly doing what im told is good, being the victim is good, standing up for myself is bad, etc.
I was trying to be healthy, but every healthy move I made violated the backwards morals of Christians. Incredibly frustrating.
Only when I realized that their submission based morals were unhealthy did I start to move out of the anger. I am replacing the unhealthy, self loathing Christian morals with morals that appreciate anything that supports a healthy life.
