I'm with you on this - seeking reassurance that I had it right (as in it's all false) in becoming "mentally out" is still good for me.
I reckon the thing that "did it" for me was the 1995 generation change. I didn't do anything then but looking back that was my "they just keep on moving the goalposts when they run out of time like they did in '75" moment.
It probably took me until about 2002/3 and going on the evil internet to realise something was really wrong and that there were others in the U.S./U.K/NZ/Aus/Canada etc. that felt and had similar experiences to me.
BBC's "Panorama" and the child abuse episode where in the UK they (the org) stopped the Watchtower half an hour early and read a letter of pathetic self-justification just accelerated the pace.
I was dumb enough to "try harder" thinking I could make a difference as an elder but then not long after I resigned.
I was quite vocal for a while but could feel the responses which made me realise that if I wanted to keep a relationship with family and friends I would have to work smart and play the long game.
This year has been better - what with jwborgtv, the ARC and "money grabbing" - and I have been more vocal again and this time I really don't care where it ends up.
I have one serving elder who I can say anything to, who is quite "in" but doesn't tell on me - an ex MS who laughs at the crazy antics of the gb with me and another ex MS who is very agitated at the way things are going and we can have very long discussions about how bad jw'ism has got.
Unfortunately my wife cannot let go - but on the upside she knows how I feel and doesn't tell on me either.
Slowly slowly ... but mentally it's great being free and has been for a few years now.
