I've been there, and still am there to some extent. I've been awake for 9 months, but there have been few outward indications to anyone that this is the case, with the exception of my wife, and even there I've tried to be subtle and take it slow.
Much of this cult seems to be designed to cause the reaction you're experiencing upon waking up - they want you to flip out and quit all at once. They want you to run to all your friends and proclaim from the rooftops "They joined the UN!" or "They protect child rapists!" or the generic but ever so accurate "They're lying to you!" This is what they want. They want you to immediately discredit yourself. They want it to be obvious that you've taken in "apostate information." They know that once someone gets to where you are, you're no good to them anymore, so the system is designed to get you out of the way fast and in a way that makes everything you say seem like it's just some elaborate apostate scheme and your mind's been poisoned and you only left for selfish reasons, etc. etc.
They force JWs to bottle up any doubts. They say the elders are there to help, but everyone knows not to go to the elders with doubts. Everyone with genuine doubts know they can't be explained away, and they know that any attempt will just make it worse and then they'll be marked as a doubter by the elders. So you bottle it up and the pressure builds until you explode. Since everything has been calm on the surface, the explosion is easily rationalized away by others as you simply losing your mind.
Don't let them win. Beat their system, play your cards close to your chest and take things slow. As others have said, time is on your side. The march of time proves them wrong every day, and only gives you more cards to play. There's no way around it - you'll lose a lot when you leave, but you may not have to lose everything and you certainly don't have to be unprepared. Make sure you have a stable footing outside the cult before you leave, and don't confirm all their expectations that you're bitter and selfish and you've been fooled and will only end up in a miserable life upon leaving. Living well is the best revenge.
Stay strong buddy, we're all pulling for ya.
