What happens if you stop paying a lease agreement, and a furniture payment?

My husband was out of work 3 months. And we are behind on mortgage, and all other bills. We put on for a modification. But since my husband is back at work they will not help us. So now they are saying they might do a repayment plan, which would double our payment. If that happens we can not afford double the house payment and our other bills. I hate to not pay and mess up our credit. But I don't want to lose our house. We have a furniture bill. And a lease item that is worth $400. And we also have an alarm system payment that we have a contract on. These would be 3 things we might start with. The furniture is a refrigerator that we need, and the lease is a water heater. Both things we needed. Has anyone had this happen, and what did you end up doing? We don't have any family to help us out.
