Hi,
I'm thinking of you and your awful situation. Stay strong! Reading your post it did occur to me that you are now in the perfect place to start a "Fade". You could start staying home for some meetings because of the stress of people judging you, but say you'll listen in (but don't!). Gradually break up the routines that they try to impose on you. Never volunteer for anything, be "sick" on ministry mornings. There are lots of posts on here about how to fade!
I had sudden pangs of anxiety and fear for years after I broke free. The armageddon fear took ages to go away particularly. It was reading up on the religion that helped me, and reading up on high control religions generally. If you watch some youtube videos on the Mormons or Scientology you'll see how many similarities there are to how they work. Then the JW's become just another high control religion and their power to control or cause fear fades away.
