I am sorry you went through some very tough times this past summer, I am happy you felt the presence of Jehovah.
I am not a JW but I am much older then you and I know how it feels to go through those tough times and know that God is walking every step with you. On my wall in my bedroom, each morning when I wake and each night before I go to bed I read "Footprints in the Sand" . I have had my share of challenges in life but God and I have walked this path together. Many times there were only one set of foot prints in the sand and I know if it was God and my trust in him seeing me through some of the really bad spots.
Before you go any further look up all the child abuse issues. I had an Elder spend 5 years lying to me before I found out the truth about this religion and he knew that I am a very strong child advocate.
There are much safer places where you can serve God. Please please run the other way.
