JK- You had a lot dumped on you at an early age for sure. The fact you were conducting a book study at age 13 was evidence of either elders dumping on you or else stalking you while conducting. That is horrific that you were abused by this elder- even having to cower under the dash to get away while out in service ! So sorry you had to go through that my friend.
One question I had : because you were the only male in your family who a JW - did your mom expect you to be the " little man " of the house , the " spiritual " head ? I know there was a time period my ex-wife did this to my older son !
Going through what you went through was REALLY traumatizing > I'm glad you have overcome it and found some happiness in life
