Respectfully I've been there and the solution at least in my case was to pull my head out of my ass, get help from other humans for medical conditions that hold me back in life, and get enrolled in college which was free for me because I'm considered a kind of, "vulnerable person."
There are solutions for America's vulnerable people that really exist. I'm proof of that if you and our respective reader don't mind me saying so.
Realistic solutions: EBT is available in my state. I don't know about yours. Local food pantries can help but one of the biggest, "poverty lifehacks" is belonging to a religious community-- I lived at a Gaudiya Vaishnava (Jaya Nitai!) Temple for some time and was fed handsomely just for being a part of the community. One's mileage may vary.
There are workable solutions to problems. Don't believe the media limbic hate machine!
