a little confused

[sandhall]

We entered a chp 13 one yr ago today. In March we let our house go back the bk pymt and the house pymt was way to much for us. I was looking at our case online today and the amount in our acct is 4 months worth of payments with nothing being paid out since Feb. My house was sold and the amt it made was exactly what the payoff is including the arrears amt of 3500.00 We got a letter from the banks attorney saying we have no debt with them. Now what happens to the the amt on the chap 13? Our attorney says nothing it stays. I had a visit with him about a upcoming issue In Aug my hubby will be medically retired from the military and we will go two months without a check so I ask if we could convert to a 7 he said no because we can just add those two pymts to end and reeval our income to lower pymts which could change from 36mnths to longer plan his retirement check is 1200 a month before taxes and insurance and my pay is no where near making up what he was being paid. How do I kept from falling behind on this plan? My spouse does plan on getting a job but it might take a few months to finish all his medical issues and be deemed able to work
