For me, as a child I did not want to go to meetings but to stay home with my dad. So I highly resented being dragged off there. I didn't like God because my dad didn't like him. So I daydreamed my way thru meetings at the age of five.
When I finally listened, I heard about the paradise and I liked that because of the animals. But just as soon as I felt like I wanted to be with God, there was a talk about how those who hated God would be destroyed! That was me! From that time on, I was doomed. My whole life became one of avoidance of reality to escape that thought. This religion also destroys self esteem by telling saying you are nothing but a speck of dust, untrustworthy, full of sin and if you are a female, less than a male.
God is also a parent that only will love you sometime in the future if you manage to be perfect.
This religion hinders you from understanding the variances of human nature. People are good or bad. In reality, they have many faults as well as positive ones.
The biggest hits for me are: the habit of avoiding reality, low self esteem and the crushing of dreams/aspirations that have nothing to do with serving the WT. Some careers take a long time to get experience and training in and that is all taken away by the WT.
