Hi and welcome thewalker. Your English is exemplary! There were no mistakes betraying a foreign first language.
Indeed most of us have been in your shoes. We had doubts which we suppressed at first but in the end needed to be examined.
The first assurance is that outside of the JW religion everything is not doom and gloom. The world is in fact full of wonderful people. The baddies though get the news exposure.
Looking forward to hearing more of your story.
One option you might consider in the near future is to step down from organisation responsibility for "personal reasons" without leaving the congregation. This will give you more time and space to do research and buy some thinking time.
