If you can get another card, get one that has low interest rate, for the credit amount that is on your current card. Then do a balance transfer. You can usually get balance transfers for lower rate for up to 1 year. Speak to your bank. If you are not eligible for another card then speak to the credit card company to arrange for lower interest rate to help facilitate the payments.
Another option available to you is if you have equity in your mortgage. Close the credit cards and pay the payments you were making on the credit cards back into your mortgage. Interest rates on mortgage loans are often the lowest available to individuals and this should mean a saving on the high interest payments of the credit cards.
