LaurenM, its because you're still indoctrinated , that's why you feel its imperative to confess to the elders. Don't make that move. It's dangerous. Rather , focus on your decision, whether to leave or stay in for a while due to family. Psyche yourself up. It's a cult and they won't understand anything contrary to their beliefs. Don't let them guilt-trip you. It's very powerful.
What convinced me to leave:
Higher education
The sole authority the GB had over all witnesses
The fact that they are not willing to hear disagreements with them
And many more.
All the best.
