If you know that you cannot pay all your debts, you could consider writing to your individual creditors to see if you can reach some compromise. Most will consider any reasonable request or offer of repayment that you make.
First consider what debts you have, whether you have money left over to make payments and whether or not your situation is likely to get better.
Always ask to freeze interest. Unless your creditors do so, your debt will carry on growing even if you are making regular payments. Show evidence to support your request or offer of payment such as medical evidence, evidence of income and details income and expenditure and other creditors.
