Scared,
I should tell you that I have been homeless before. Living on the streets is not easy. Avoid getting sucked into groups of people who may use you or drag you down such as drug addicts, etc. Find successful people, and ask them for help. There are other groups out there besides religious organizations, but those are the ones I found most helpful (besides the welfare programs) in helping me get out of poverty.
Also, JW's love to pull all support from df'd ones. They think the hardships they cause in people's lives will be God's doing. They rejoice when people who leave suffer. It is a cultish ploy to get you to return to the fold. Don't give them the satisfaction. The best revenge is to live a good life. Plus, screw revenge, just live a good life period!
You can do this. Many people have. You are more than a suit and pamphlet passing robot. You are smart enough to realize ttatt, and brave enough to express your doubts to elders, so I think you will do well on your own.
