Before field service I would feel physically ill and usually try to get out of going. I would sometimes get physically ill before conventions and assemblies, especially if I didn't know many people there. Turns out I suffered from social anxiety! Too bad I didn't know that then.
To avoid people at the meetings, I would hide out in the Mother's Room once I had a baby. Turning down the volume in the Mothers Room to block out the speaker gave my mind the space to free myself mentally from the religion. And once I learned TTATT, my heart would race at the meetings and wouldn't stop until I left. That made fading super easy and quick!
I bet lots of people suffer from anxiety at Hall. It is an anxiety inducing environment.
