From the outside distrust is just embedded into the JW mindset. Over time that may change.
Scared and lonely, as a non and never have been JW, my recommendation to you is to stay grounded in what your goals are. Someone else's inability or apprehension to trust you IS NOT YOUR PROBLEM. Do not add to your existing challenges by making their problems yours. And STOP apologizing.
"I'm hurting." .... "you're a liar AND a troll!" It's like I'm watching Trump in a debate.
Personally, I don't need protection from the self appointed Troll Police Force and I'd be glad to make myself available to help you understand the general mindset of non-JWs from my perspective.
Let me know how or if I can help you.
