I couldn't tell you. I have known they were wrong for about 10 years. I have been on a serious fade for several years now. I used to really HATE them, slowly I believe I am moving more to a feeling like I just don't care anymore, but I am not there yet. As long as my wife and daughter are being mislead by them I guess I will lean towards the hate side. The only thing is, it is kind of like when you break up with a girlfriend or wife. As long as you hate her that means in some way you still care, when you get to the point you don't hate anymore that means you just don't care about them one way or the other. I think that is the goal.
One way that might help ease the hate you have is to remember that 95% of the JW's are simply being fooled themselves. I think even many on the GB believe thier own delusions, and if they don't what a miserable life that would be! Look at Rutherford, he was not deluded, he knew what he was doing. Yes he had nice cars during the depression, yes a lot of people looked up to him. However his own son would have nothing to do with him, his wife would have nothing to do with him, he was a drunk and he died of ass cancer. Plus when he died according to AC McMillian only 3 people went to the funeral.
So I guess when you get pissed just remember - Ass Cancer - that will make you smile.
BTW. I agree with the elderlite, getting professional help is good. I had some issues several years ago and 6 visits to a therapist helped me tremendously.
