There appear to be more important things to be concerned about than your debt situation at present,and I do hope that you and your wife manage to sort out your difficulties soon.
Debt can lead to so many other problems - marital, health, and stress related issues, and sometimes it is wise to just park the debt issues and put things into perspective in order of priority. Try to remember the difference between a house and a home - they are not always the same, and as they say a home is where the heart is and if that has to be rented accomodation for a while so be it. If your family are around you that is the main thing.
As you say a lot of your stress has been brought on by having to work lots of overtime to just cope with the ongoing payment of unaffordable credit. Perhaps it is time now to consider what positions you better for the future, be it a structured payment under an IVA, or the fresh start afforded by bankruptcy proceedings.
