For me, I suffered with depression/anxiety and felt burdened by the guilt of the TRUTH .... every way I turned, guilt was heaped on my shoulders. I had problems at the meetings (couldn't answer-up/couldn't join in basically) and I know that this was frowned upon. Matters just got worse & worse and I felt more isolated with my problems. I started drinking, daily, and eventually shut myself away.
The brothers around me at that time had no idea how to handle me and obviously the advice was - go out in the ministry or have faith in Jah etc .... not at all useful for me personally.
I was also told by a loving sister?!? not to seek professional help for my troubles - council outside of the organization, was likely to be guided by Satan to lead me away from the TRUTH. The same (mad!) sister who once told me that she had demonised bed linen - don't ask !
I then witnessed terrible hypocrisy through so called brothers?!? Who were getting up to tricks, that I could not reconcile with Christian faith. Heavy drinking, messing around with sisters and general back stabbing.
I can appreciate the view that brothers were mechanical in their dealings - I saw this as well - devoid of fellow feeling for the most part. A show of empathy, but nothing that went below the surface.
I then met a sister who was nearly exploding with the burden of the truth.... and basically, we crept off together and vanished.
