Hi Jake,
First of all welcome to the forum! It's great to have you here.
My advice to you regarding the nagging "what if's?" you are feeling - is to hit the,books and do some research. True knowledge is a powerful force, and once you gain a full understanding of things! those nagging "what if's" completely disappear and are in fact replaced with an an extremely powerful feeling of inner peace and a great sense of "relief" for having avoided a very unsavory life trapped in a religion like the JWs.
I served as an elder for many many years, and then was shocked and horrified to learn that the religion I had devoted my life to was false.
Jake, I strongly encourage you to continue your time here on this forum and to thoroughly research the history and teachings of Jehovah's Witnesses. You can decide for yourself what is true and what is false, but you cannot fall in to their trap of relying ONLY On what they tell you. This is not reasonable and is a tell tale sign that you may be getting mixed up with a cult.
Welcome again Jake, and good luck on your journey to find real truth!
