Good for you Ignoranceisbliss. Shutting down your brain is exactly what a cult wants it's members to do. They like having brainless drones.
Keep your brain alert and formulate your exit plan. Watch your loved ones at the meeting, see how much they are involved. If they participate talk about their comments to test the water, if they don't participate this is good, they maybe on a brain shutdown too. Ask them how they feel about participating in meetings.
Stay awake to WT rituals, and protect your brain.
Take care
