Welcome Ahava.
From what you've written it seems you like structure and are not so worried about facts. Do not limit yourself to information provided by the object of your research, ie: "The GB are Jehovah's spokesman because they said so". This will explode in your face if you get baptized and then you find the facts they presented you were false. You will be reviled, ignored and become an object of derision. Give it time. If you are studying with them take an extra long time studying before baptism and see how their interest in you will wane as you ask pertinent questions. I would ask, "will JW's still believe in doctrines 10 years from now that they believe is truth now? What if they change their belief in a life or death matter and were wrong all along?
Unless you are easily used for their gain via money or prestige you will be dropped.
