Well done Akid for finding this site--and welcome!
I started to get involved at your age and boy do I regret it. The worst decision of my life. Believe me after wasting years as a deluded member of this cult I am so glad I escaped and started to live again.
Let me just say that the teachings of JWs are all intended to make them servants if not slaves to their leaders and their teachings. JWs will strongly deny this because they can't see where they stand from being firmly stuck inside the organisation knowing that there are threats of punishment should they start to question the doctrines.
I'll be brief; the Bible is hopelessly contradictory and a work of propaganda, not surprising then that Christianity and JWs follow the in the same pattern; asserting things to be divine truths but what is really only propaganda. The lovely promised paradise is just too good to be true, it is a utopian dream, it will not happen and neither will Armageddon, they are fictions.
I wish I knew these things before I studied with JWs.
All the best to you as you learn that adult life is more complicated than you were thought. The best answer to all these questions is to learn to be able to understand how to distinguish between what is true and what is religious salesmanship...in other words do aim to get a good college education and learn that truth starts and ends with evidence not faith.
Do keep posting and let us know what you are thinking.
