hence the stuff about "God" in the letter

"I think she's looking for someone to blame for what she doesn't like about herself." In my book, that's a resentment and that is exactly what Step 4, which is shadow work before that term became popular, is designed to work through, which is the opposite of what her cultish church is doing.

Anyway, I hope you'll be able to keep in contact with your granddaughter now that she's an adult.
