Listen to my podcast ThisJWLife and maybe you'll feel less alone. Reach out to others here like you're doing. Start making friends outside the cult. Maybe find a therapist in person or online to talk to. And do all of this as preparation to leave the cult for good.
Let it go. You've got to know when to hold 'em, know when to fold 'em, know when to walk away, know when to run. Yes, I just mashed up two songs, but the point stands.
Your options are, as you presented, to leave this earth or leave the cult. Leave the damn cult and go live life. The choice is obvious. Start preparing and let go of the things you're holding onto so strongly that they're taking you down with them. You will feel so free if you do.
