Tbh, I did try leaving once (the details are for a different post). In a nutshell, I told my family I didn't feel comfortable being a Witness anymore, and I simply left and stayed elsewhere. At first they cut off my phone so I'd have no contact with anyone else (because they were punishing me for eating with a male friend), and they made me call my ride with them listening on their home phone. I left and for a few hours I was okay.
Then my phone magically turned back on. Then came the pleading calls. How my father misses me and has barely eaten or slept. How they just don't understand why I'm throwing everything away. How I can't afford to go to college and have a roommate on a disability check. And they told me they'd contact the SSI administration so I'd have my disability check revoked due to my new status as a roommate. I was already on an emotional rollercoaster, and their calls made everything worse. They kept going on about how I'd be dead and they'd be enjoying paradise with my deceased grandparents. I know it's all bullshit, but they sounded completely depressed about it, like they genuinely believed if I was no longer a JW, I was good as dead and they couldn't stand the thought of living without me. I felt so conflicted because when I left, I tried hugging everyone. My dad gave me a big squeeze, and my mom just pushed me away and gave me the cold shoulder. I was shocked and thought they didn't love me at all. And yet here they were, pretty much begging me to come back at least until I was more stable.
And despite them showing me their true colors, I came back. I know I'm weak. But they fully buy into the whole JW life/death thing, and my leaving kinda traumatized them. It's been a few months since I tried to leave, and I somewhat regret my decision. But what can I say? I guess I love too much...
