Welcome Huxley! Glad you found us.
I was in the audience at Dodger Stadium when Freddie Franz yelled into the microphone "this old world will not survive the end of this century!" And by george, I believed him 100%. As a JW you only look for and only see the bad going on. You are taught to hook onto it so you can offer a pet lion on a paradise earth to worldly people. And boy did I. And I was successful in converting 4 people to the faith.
One of the major factors of my leaving was a series that was played on PBS in 1999-2000, about apocalyptic religions. It traced many groups through the centuries predicting 1000, 1500, 1844, 1879 etc etc. as THE year of god's great war with satan and "their" faithful as the only worthy survivors. I had no idea. I was raised a JW, and I thought only they had the inside scoop on this whole business. Turns out JW's were just one of many groups that interpreted scripture to their own agenda, each with their unique argument as to why their calculations were the only correct ones.
As read and gather more information outside the JW box, you will gain more confidence in your decision.
Wishing you peace of mind and comfort for the journey.
