Okay well this might not help but I have a suggestion. It's complicated, but I've been receiving food stamps in Florida for quite a while now, because I'm disabled. But hear me out, because you don't *need* to be disabled to get them, and it gets interesting.
It gets interesting because, in Florida, they passed a law recently stating that if you are able bodied you can receive food stamps for a certain period of time and then you have to get a job to continue receiving them. I'm given to understand this is happening in other states as well. (Like I said, it's complicated, so keep reading!)
What they do is, you sign up for food stamps. You will get approved for expedited or emergency food assistance benefits if your living expenses exceed your income, which they would for someone with no income. They'll send you a letter in the mail or a notice online (whichever is your preference) stating what you get per month and for how many months you're approved. (Commonly, people have to reapply every four months or so. nbd if you do it in a timely manner.)
Then they'll send you another notice stating you have to work to keep getting your benefits. They'll give you a website to go to and an address to go to if you're unable to do the web orientation. You'll put in your work experience and skills and so on, and they'll help you find a job/get in on some job training/etc. As long as you're *trying* to get a job or cooperating with the program, they'll keep your food benefits going.
Someone else suggested you consider taking college/university courses, which I would second. You can get student loans and grants from the government to help with that. For me, I often got excess financial aid while I was in school, and with that, you can do whatever you like. I also used my aid to find a place to stay, etc, usually on campus but sometimes elsewhere.
With the university stuff, you can just pick whatever major you like at whatever community college or bigger uni type place, and just take gen ed courses at first. Then later you can maybe pick a different major after you've had time to really think about it. Or you could drop out after a semester if your situation changes or you decide that's the thing to do. Like I said, you can get grants and loans or one or the other, and I know having loans is unappealing, but listen, if you can do that, it might be the difference between having a place to stay and not.
