Welcome, Sarabi.
I, like many others, have gone through similar emotions to the ones you are experiencing now. My younger sister first came to this site and told me about it. I, of course, sought to be the protective older brother and was angry at my siter for reading "apostate" material. However, when I got to the point in my life where I couldn't rationally reconcile questions I had with the pre-churned answers that the WTS provided, I began searching. I lurked at this site off and on for about 2 years before I actually joined and began posting or speaking of my concerns with others.
No one drove me to stop attending the KH. That was a decision that rests soley on my own shoulders. At this site, and others like it, I began discussing my questions and doubts. I spent a period of time researching. I spoke with my wife - still a JW to this day - and she agreed that taking time to work through my questions and find my own answers was the best thing that I could do. She gave me space and realizes that we differ on religious beleifs, but she lets me form my own thoughts and reach my own conclusions. At the same time, I let her have her own beliefs...even though those are JW beliefs. We still are close. She doesn't consider me an "apostate" in the sense that the elders would.
No one should be afraid of truth.
