Use dry beans to make soup, it's warm, filling, and inexpensive. Watch for good sales on the meat items you need.
Start a potluck/game night with friends. It's fun and won't cost much if you all contribute a food item. I can tell my true friends when I can't afford to go out to dinner and a movie, and they can tell me. We play Mexican Train, Scrabble, or just a game of cards.
I'm working from my stash, only, at this point. But it's still comforting to have sewing in my hand and I love the fabrics I already have.
Check if your local library sells old magazines inexpensively. Something new to read and usually cost very little.
Good luck and hang in there.
