It's a bunch of gobbledygook about the generations and the kingdom and all of that. It's all nonsense. In my humble opinion, you need to de-indoctrinate yourself to fully remove these types of fears. Not sure if I've shared this post with you before, but here's what I did personally:
Take some time to learn about the history of the bible. For example, you can take the Open Yale Courses on Religious Studies for free.
Read Who Wrote the Bible by Richard Elliott Friedman
Also read A History of God by Karen Armstrong
Next, learn some actual science. For example - spoiler alert: evolution is true. Visit Berkeley's excellent Understanding Evolution Website.. Or, if you're pressed for time, watch this cartoon.
Read Why Evolution is True by Jerry Coyne
Read The Greatest Show on Earth by Richard Dawkins
Learn about the origin of the universe. For example, you could read works by Stephen Hawking
Read A Briefer History of Time by Stephen Hawking
Learn about critical thinking from people like Michael Shermer, and how to spot logical fallacies.
For good measure, use actual data and facts to learn the we are NOT living in some biblical "last days". Things have gotten remarkably better as man has progressed in knowledge. For example, watch this cartoon explaining how war is on the decline..
Read The Better Angels of Our Nature by Steven Pinker
Another great source is the youtube series debunking 1914 being the start of the last days.
Another way to clear out the cobwebs is to read and listen to exiting stories. Here are some resources:
Here is a post with links to a bunch of podcasts interviewing JWs who've left
Here's another bunch of podcasts about JWs
Here is a great book from Psychotherapist and former JW Bonnie Zieman - Exiting the JW Cult: A Helping Handbook
I wish you the best. There is a whole world of legitimate information out there based on actual evidence that you can use to become a more knowledgeable person.
You may still wonder how you can be a good human without "the truth." Here is a good discussion on how one can be good without god. --Replace where he talks about hell with armageddon, and heaven with paradise--
To go further down the rabbit hole, watch this series.
Here's a nice series debunking most creationist "logic".
Start to help yourself begin to live a life where, as Matt Dillahunty puts it, you'll "believe as many true things, and as few false things as possible."
Here's another side of the coin. Not necessarily to drag you out of the cult, but just some very awesome, beautiful truths. If you've seen me post this before, i apologize. I don't like to assume everyone reads every thread.
> "Who Wrote the Bible?" by Richard Elliot Friedman beforehand
I did not do this, but by the time I'd read "The Early History of God", I was already well aware of the multiple pagan origins of  much of the bible, the two creation stories in the book of Genesis, the astrological significance of the "12" tribes of Israel, the volcanic origins of some of the Israelites' god's characteristics & rituals, and more.
I'm going to check that book out, though - here's a readable preview of it:
Keeping in mind that amazon likes to sell books... I assume you buy used books whenever possible?
