Welcome to the site and your doubts are right about the Borg. I understand your plight of knowing nobody on the outside. My family goes back since my grandparent's grandparent's in the troof. Or wait...maybe earlier than that...anyway, If you must leave do it 100%. Think of all that energy you spent trying to make new JW's and counselling already JW's. Leaving will be much the same way, except you will be making friends and building a network.
If you are to be kicked out, you will need to find food and shelter. Immediately, you need to put together a resume, and find employment. Next, if you are in the USA, find the number to your local food bank and government assistance programs for welfare recipients. If you are in any place in the world including the USA, you can go to a local Catholic Charity and receive food and perhaps shelter and info for other charities. This is just a start.
You must form a network. Try to find other ex-JW's in your area. You can do this with the app "Meetup". You can also do this on this website. Most places in the USA have a community church. Where I live the community church is huge (think lots of $$) and the place to go if you need help. There are many small groups that meet for various reasons at these churches, and you will find tons of people receptive to your story and sympathetic with your plight. I have done this before--just went to some women's groups a few times and met some amazing individuals that are now my good friends. They don't care that I don't attend their group anymore, but we always find time to hang out and help each other.
If you know you have no chance to fade, then these are my suggestions. I am currently fading nicely. Hope this helps!
Edited to say: Each state in the USA has its own sort of welfare. And trust me, some states are better than others. If you are planning on moving, I would look into finding a state that has plenty of jobs (a bustling economy) as well as excellent welfare programs.
