No wonder you feel alienated, Dee.
I have a feeling you are more authentic than most in your group. True self esteem doesn't magically emerge into existence over a few weeks, or even months, no matter what a person does or believes in, imo. This group sounds all peer-group pressure and brownie points for saying that you are getting better, way beyond the truth of what it is to struggle and work on yourself at depth and with sincerity.
I'm happy for people to talk about their faith as part of recovery, but I would resent having it rammed down my throat. It must be really hard to be in a group that shares a common faith and relates most experience to it. I couldn't handle that and I'm sorry you've experienced it. The facilitator sounds way out of her depth with trauma work.
I don't think you are layers below, Dee, I think you have great integrity and are able to be honest. If this is a trauma group, it sounds like honesty is in short supply, and has been substituted for the glib and superficial, with stars and stamps for good behaviour, and, imo, that is never going to bring deep healing.
