Hi fergie - and welcome to the forum
You clearly need to take advice on your overall financial situation, as it appears that you are insolvent on the basis that you cannot afford to pay your debts when they fall due.
This may be a temporary problem, and therefore by talking to your creditors and explaining the reasons for your current problems, you may be able to buy a bit more time to pay the instalments.
If your problems are more permanent, and you have been having difficulties in paying the loans for some time, then you need to take advice from an insolvency practitioner or debt management specialist.
Are these your only debts, or do you have others?
