Extreme hunger pains, and absolutely NO money to afford food, need a membership to access the food bank?

I have nothing, i live in a homeless shelter and they never provide food, only small snacks just to get by, and they never let me use my welfare/foodstamp money or else theyll kick me out of the shelter back on the streets again.Local food pantries around here require a membership, and currently they say they have no more memberships. What do i do, eat the plants outside? Is that nutritious? And will i throw up? Please help me, its hard enough starving the other days but today they had no snacks left and i'm HUNGRY! People usually always ask me on reddit how i'm on the internet. And to tgose people: I HAVE A INTERNET CARD FOR MY LOCQL LIBRARY! Nothing against anybody but i get fed up because they think every homeless person can't go on the internet, of course they can. There's this one homeless guy with a cart who stinks and goes to the library everyday and has an expensive mac computer and iphone 6.Anyway, please help i really am starving, what can you guys suggest me do, thanks.

Added (1). oh and the reason i put this in the law category is that i know a lot of police officers know about homelesses and this kind of stuff.So thank you

You should be eligible for food stamps.
