Jessica, Go to your local churches. Some of them have what you call food banks. Most churches will find you help since you have a child.
Also check to see if you have what is called F.I.S.H. in your area. That is run by church groups.
Also, Sheperd’s Staff. They are also a place that will give you food every week and give you financial help ( for a bill like gas, water, electric ) every 90 days. I don’t know where you live so I don’t know what is in your area. I hope this helps.
If I fins out any other places, I’ll post it. Good luck.
