I agree with the others when they say don't even think about broaching the subject with an elder unless you have some idea what you are talking about.
Oh, and Smart? Take deep breaths in and out. I understand why this knowledge can hit you like a brick and send your emotions all over the place. You are lucky, though. You are young. You have no JW family. You have only been baptised 2 years. You can come out of this relatively unscathed (compared to long-timers and born-ins) and start living the rest of your life.
Any more questions on this subject, no matter how 'stupid,' don't be afraid to ask. We're here to help :-)
