I cried the first three meetings I went to. (I hate that, but I KNOW that means I'm in the right place.) It is stirring up TRUTH for us. And definitely fear (being scared). Fear of facing the truth about our compulsive overeating.
At least that is my experience. I do hope you keep going back. I finally went yesterday and didn't cry. I teared up a little when another person was speaking, but no bawling this time.
Oh and by the way, you never "have" to speak in a meeting. It is completely optional.
