The thing that tears you apart is realising that you have been controlled your whole life! That you have believed your whole life that you have the truth and no one else does and realising that it is a fallacy. I'd always had some doubts, many JWs do, but they are always put to one side. The thinking is 'Jehovah will sort it at the right time', the 'light will grow brighter', 'wait on Jehovah'. I always believed as do most JWs that the 'Faithful and Discreet Slave' was being directed by God (even though not inspired of God like the bible writers and even though still imperfect men). The idea is that if the guidance comes from God then you don't question it.
For me the doubts became more and more until one day I stumbled across Ray Franz book 'Crises of Conscience'. I read it out of curiosity at first. What JW doesn't have some curiosity about what goes on behind closed doors in Brooklyn? When I started to read it I still believed it was 'God's Organisation'... by the time I finished it I felt as Dorothy must have felt in the 'Wizard of Oz' when after all her struggles she found out that the Mighty Wizard of Oz was just a little trembling old man behind a curtain. I was left shaken, as many others have too. After that you can see through everything but at the same time you feel trapped because there is no easy way out. You either stay and pretend and try and fade as best you can or you leave and risk losing everything. I'm talking 50+ years of everything here. Those who have gone down this route will testify to how painful this is. You gain your personal freedom at great cost. I am still very much a christian, in fact more so now than as a JW as I accept Christ as my personal mediator.
As for 'laying on of hands', the WTs believe that this came to and end when the apostles died. So this is not done at all. It is deemed as having something to do with the 'demons'. There is no ceremony at all. The person to be made an elder will be approached before the meeting, asked if he will accept becoming an elder and if he does it is announced that he has been appointed. That's it.
