Oh hun I'm with you on this, I feel your pain.
I was never an elder as I'm a sister but I was highly respected by the elders in the cong for being down to earth and talking sense. It was a total shock to the cong when I left. I just wasn't the type of person that could pretend it was the "truth" and fade, I had to go cold turkey.
If you too aren't the type to fade, then please be prepared for some serious flack, If you disassociated, then the shunning may be more hurtful than you anticipate. It was for me. I naievely thought my "friends" of 21 years wouldn't do that to me, oh boy was I wrong!! I have spent the last year being badly hurt by the shunning. I stupidly still sought JW approval and set myself up to be rejected time and time again.
Then my mum (an active JW) got cancer. Instead of helping me the sisters literally turned their backs to me as I passed them. That finished it. They showed their true colours and I finally let go.
I physically left the orgainzation a year ago, I emotionally left 2 weeks ago.
So please think carefully about the course you take. I am glad I disassociated despite the hurt, as its proven beyond a doubt that this org is not only wrong, but positively evil. I am grateful every day to have escaped its clutches and listened to the words of Jesus at Luke 21 v 8
If you do decide to disassociate, then may I suggest you get a support network in place first. Friends from work, join a club, have somewhere else to go on Tuesdays and Thursday eves. Be busy.
Most of all, if you still have a belief in Jesus Christ, then trust him. He said come to me all you who are toiling and loaded down and I will refresh you. He meant it.
I also agree with ESTEE, Crisis of Conscience and In Search of Christian Freedom by Raymond Franz are a "must read". It'll answer many of your questions.
best wishes
