Min. I feel for your mother.
My grandmother gave her whole adult life to the WTS, pioneering for the most part, regular publisher into her 70's. But towards the end, as her health began to fail, she came to realize, that JWism was a farce.

"Religion is the worship and service of the Devil and his associate demons .... Religion is the chief means that puts fear into the minds of the people and leads them into the Devil's snare .... Truly then, as stated, 'religion is a snare and a racket,' employed to collect money from them under false representations." Joseph Rutherford
