You are not alone. You can get help through reputable groups such as CCCS (I think it stands for Consumer Credit Counseling) - they negotiate with credit card companies on your behalf to cut your payments and interest rates. You just pay THEM, and they pay the credit cards. That stops all the annoying collection calls too. If you are paying the minimum, it never goes away.
I would get rid of the cards entirely so you can't slip. You could also work from home, as I do, helping others and making a great profit.
Don't buy convenience foods - they are way overpriced. Switch from brand names to store brands unless you have a triple coupon that makes it worth it. Don't buy soda at all - overpriced sugar water. Don't buy snack sized anything (make your own). Don't use paper towels (use absorbent cloths you throw in the wash - better for environment too), cut out your daily paper (use the internet), cook more using real food (make it a family activity even if it means cooking on Sundays and freezing for the week), make coffee from home instead of going to Starbucks. Shop at a supermarket that gives gasoline credits. Have a family movie night with popcorn and a DVD instead of going to the theater, invite friends for pot luck instead of going out to dinner. Have a neighborhood yard sale and get everyone to chip in on the cost of the ad. Call your phone company and internet provider and ask them for a less expensive plan. Go to the library instead of buying books. Take clothes you don't wear to a consignment shop. Take kids' toys to a resale shop.
We have been pushed by the predatory lending companies to buy homes we really cannot afford, and so it's no surprise that so many people have ended up in this situation. Some people still think that the industry doesn't need to be regulated (like that will stifle the economy) but the economy isn't moving when everyone is paying interest instead of buying goods & services. We have some responsibility, absolutely, but there is a whole lot of unethical business stuff going on too, all that stuff in the fine print.
And, we think we need everything NOW. You'd be surprised at how you can get by with a heck of a lot less. Teach your kids that it's better to work for something than to buy it now and spend a lifetime trying to pay for it. We are killing ourselves with stress in this country, and we have to stop.
