Hi dave and a warm welcome to the forum
You have negative equity in your property, and the most important payments to continue to make are those to your mortgage company and secured lender, as these affect your home.
Have you sat down together and worked out an income and expenditure account, to see if there is any surplus income left at the end of each month once you have taken account of the household bills and other general expenditure - including shopping, car expenditure and clothing. If there is some money left, then you might be able to propose an IVA to creditors, but bankruptcy is also an option.
I suggest that you take more specific advice from an insolvency practitioner, who will be able to look at your case in more detail, or post more details about your income and expenditure on the forum and we will try to help.
