If your credit card is out of control, seek help.
Abuse a credit card, and you can end up bankrupt. If you find you can't control the debt, take prompt and serious action.
First, stop using the card. Cut it up if need be.
You should then speak to your bank about restructuring the debt. One option is to set up an automatic payment to pay it off.
Another is to add it to your mortgage. If you do this, make sure you repay it as soon as possible, or your gains through a lower rate of interest will be undone by the longer time it takes to pay off the debt.
