If you feel that this house is a millstone, and are happy to move back into rented accomodation, I would give this serious consideration. This may well then leave you with sufficient surplus income to repay your debts in full, without resorting to either a Debt Management Programme or an IVA, but if not then with no assets you might also feel that bankruptcy is a better option.
As the other posters have already suggested - work out a present and future income and expenditure budget to see how much you can afford to set aside towards creditor repayments each month, and consider taking advice directly from an insolvency practitioner with regard to your options.
