My hubby and I farm, have 4 kids. We have had some nature disasters that have us in danger of losing our farm?

We have fallen behind on a loan because of a snowstorm where we lost livestock, and an elevator that we sold commodities to that filed bankruptcy without any warning to us. So we haven't had the money to pay on this loan. Last week our banker emptied our checking account to pay some on the note. The amount he took didn't even cover the note, therefore overdrawing our account. I don't even have money to buy groceries for our family. What can I do? I need to know if there are any sources out there that can help us out. We are not the kind of people who have ever even considered asking for help..and now we are in danger of losing out livelyhood and our childrens future as our 3 sons would eventually like to farm.
