I'm a lifelong atheist and I grew up in the South surrounded by Southern Baptists. I hated it when people invited me to their churches or retreats or when they asked about my faith. I felt like a freak but my beliefs never wavered.

I met someone who has PTSD due to his Mormon upbringing. He described it as a cult. He was always paranoid that everyone around him was Mormon, maybe keeping tabs on him. He also had nightmares, flashbacks and dissociation. He was unsure if he had been abused by men in the church.

I don't know how you would do this, but I think you need to find a therapist who isn't Mormon. Otherwise, he'll be biased or you'll believe he is biased. Also, I don't know if this is feasible, but I feel like it might be helpful for you to move to another state for awhile. Take a contract job for a year, get away from the constant reminders of your oppression. I know it's easier said than done, but I just wanted to put it out there. I live in a pretty atheist/agnostic area now, and it's such a relief.
