"They seem to think that my desire to leave is simply because I have "hurt feelings over being disfellowshipped," and that I "lack the humility to accept discipline," so I've clearly made no headway in convincing them that this is an informed decision, but ah well, at least I don't have to feel like I'm living a lie anymore."
They all use this one! Makes you want to scream! What they are saying is "it's your fault." It is the JW way. Tell them, "what kind of loving organization kicks their members to the curb?" The world doesn't even do this to you when you need help.
I'm glad you had the guts to do this. You spoke your mind and that is great. It hurts but you stood your ground.
