If you are struggling for food, do not be afraid to ask for a little help. There are food pantries (almost) everywhere. I’m talking about the US.
Ask the library in your neighborhood. Ask a church near you, even if your not religious. If they don’t provide support they will know who can.
It’s nothing to be ashamed of. You need to eat. And no one except other people that have needed support even knows what’s going on if they see you lugging home pantry food.
If you need help, ask for it. People are happy to help you if you step up and just say hey I need a little help this month. If you know you need food, get it.
