Dearest lits,
I really feel for you and the situation you're in...do you have children? I was born in the org, pioneered, married at 22 with a brother (a marriage that was never truly happy). I left the org and him last year after 12y or marriage. we had no kids. It was truly hard but I just knew that for once, I needed to put my life and my happiness first. (as a JW this is hard, we've learned not to be selfish etc especially sisters unfortunately). So I dropped everything and just listened to my heart. I finally dared to think that perhaps this is not the truth after all. God could not want me to be so unhappy. I came on here and saw I wasn't alone. That is what you have to do. You deserve to be happy. Like you say, it's horrible to realise that you may have wasted your life to a lie. So many on this forum have dedicated almost their whole lifes in the org but the FREEDOM you experience when you leave is worth so much. We only have this short life and we owe ourselves to be happy.
Is your whole family JWs or do you have someone you can talk to closeby and who can help you?
Be strong
