I will say the biggest problem is social interaction. As a cult organization, JWs broke social network with their families, friends, peers, and dedicated their social ties to organization only. This cut them off from external environment and created delusional world of reliance among JWs only. Many members do not know anyone outside the KH and this makes the break difficult. This is especially true for older generation that lacks technology to interact in era of Facebook and mobile apps. My mom is almost 80, she knows that WT is much of BS as she does not recognize it as the same organization that she was 40 years ago. We have aunts, uncles, sibling, cousins in. If she leaves, she is afraid to lose social contact with them. My cousins who are elders will shun her. She may lose interaction with grandchildren. However, the younger generation is not as totalitarian self-sacrificing group as the elderly of the Knorr era. There is a hope that these people will have much easier way out and would not even bother with the KH social network.
