Welcome!
I can definitely relate to the adrenaline rush of that first post and the paranoia that came with signing up on this site. That in itself really says something about this cult - the fact that almost everyone in your position relates a similar feeling of fear as a result of that first post really shows how controlling this cult is. When even anonymous speech is a frightening concept, something's wrong.
As difficult as this process is for anyone, it sounds like you're in a pretty good position, all things considered. Definitely keep learning and researching, but remember that there's no rush. Just because you're leaving one belief system doesn't mean you need to jump into going to another church or whatever. It seems that a lot of those that leave still have trouble with the concept that there's time. Armageddon isn't coming, and you have time to figure things out at your own pace.
I wish you nothing but the best on this journey.
