I remember how after decades of knocking on doors and auxiliary pioneering, my Mom finally found someone to study with that was actually making "progress". She was over the moon when this 20 something young woman started coming to meetings. It was as if she had a new purpose in life.
After a few meetings, another sister in the Hall befriended the young woman and talked her into studying with her instead. I remember my Mom going into a deep depression over this. She was hurt that the other sister would do this and that the young woman would agree to it. She began to feel that Jehovah wasn't blessing her efforts for some reason and quite literally took to her bed for several months.
It was awful...my fun beautiful fashion model-like mother got extremely thin and couldn't even bathe herself or do her hair. My Dad had to go to work and didn't know what to do for her so it was up to us kids to look after her and the house. Back then, JW'd didn't go to doctors about this sort of thing. They believed that reading and applying scriptures and prayer was all that was needed. Some of the other Sisters used to come by and admonish her with scriptures and eventually they convinced her that Satan was testing her faith and that she was failing. They convinced her that the important thing was that someone was studying and it didn't matter who was studying with her.
Little by little she came around but she wouldn't go back to the same Kingdom Hall. We eventually started going to another Congregation so she could make a "fresh start". She was never the same about "the truth" after that.
