I would say most would do better to see a therapist even if they don't know it.
I agree, there's so many walking wounded ex-JWs who pretend they're fine. My inlaws mentioned earlier tried to act as if the 55 years they spent in the cult never existed. They even made themselves believe it up to a point.
At one of my daughter's birthday parties they said it's a shame we didn't have parties like this when our children were small, I'm not sure why. Perhaps it wasn't done so much then. I said it was because you were JWs remember? They looked at me bemused and said vaguely, 'oh yes, forgot about that'!
