First off, don't beat yourself up. We all make money mistakes, put that energy into wanting to make it stop and live a better life for you and your family. I'm on the Dave Ramsey plan, and so far have paid off 3 ccs this year, 5 more to go. Go to your library and check out "total money makeover" his book. Very easy read, inspirational. There's also info on daveramsey.com
It's a 7 step plan, and it has made bill paying a good day of the month for me now. Every month everything I can muster goes to paying off debt. When one gets paid off, it is a happy dance! It's set up so you pay smallest debt first, so they are done and out of your life. woohoo! so you feel the momentum right away and you want to do more. You then take what you were paying on that debt and roll it up to paying that much to the next debt, so on and so on.
Anyway, good luck. Pat yourself on the back for wanting to make a change!
