I have always had doubts but was always told to wait upon Jehovah and just trust the governing body. I had a crisis in my life that forced me to reconsider my whole life decisions and beliefs. I questioned everything. It made me realize that religion is not the answer and that WT is just another business. I didn't realize how much I was looking to WT as I would God. The WT was my god. I also realized that pretty much everyone I know who is a JW has this feeling as well. My journey isn't over but it's been a rollercoaster that has been gradually stabilizing.
I still believe in Jehovah, Jesus and I'm restudying the Bible. I feel like I had to start from scratch. This time I'm open minded and willing to see ALL facts. My faith is still there even though it did get trembled. I find myself praying, reading and studying more.
A book that really helped figure myself out was The Subtle Power of Spiritual Abuse. It helped me analyze myself, my emotions, my thoughts since I felt so overwhelmingly scattered by the life crisis I was going through. Crisis of Conscience, In Search for Christian Freedom also helped process my thoughts towards the organization.
I find it absolutely fascinating to study the Bible in a different light. I've been reading on the books in the Dead Sea Scrolls, secular history while learning greek and hebrew. I'm not an expert. I just think it's interesting and fun.
