Have you tried applying for benefits thru here or speaking with some type of advocate for your situation? If you're in Providence, I believe they are more lenient about getting benefits to immigrants.

If you're in need of food, there are food banks in every town. You'll need proof of address so try to get an official piece of mail to an address in the city- phone bill, something from the state, anything but junk mail.

Churches also have food banks. You can contact any location of Saint Vincent de Paul and they'll usually give you a box of non-perishable foods.

During this cold season, there's also locations that give out winter coats and other things. Try finding more info on that.

Housing in very expensive in RI right now, like most places. Do what you can to make it through the winter with a roof over your head. There are shelters but they're not all pleasant and mostly just have beds for men during the winter. There are very few beds in the whole state for women.
