When I found myself with major debts, I discovered that some of my fixed bills weren't really fixed and that I could get along without some of them. Sometimes you can find a cheaper internet service provider, or get a cheaper rate by cutting out the frills. Is the electric bill slashed to the bone? Do you unplug the TV when not in use? Do you have a long distance phone provider that doesn't bill you at all unless you actually make a long distance call, and can you simply refrain from making such calls?
Check out food banks and cooperative buying groups for food. Some have maximum income requirements or require that you put in volunteer time, but most do not.
Calculate driving expenses (include maintenance, insurance, etc.) and see if it would be cheaper to use public transportation for all or part of your commute, or if there are van pools. If you're in a rural area with extreme weather, you probably need a car, but most people in urban areas do not. Rural areas usually allow pets and livestock, urban areas don't, but suburbia is the worst of both worlds, where you're not far enough out of the city to have the advantages, but far enough away to have to commute.
Are the prescription drugs really helping? I'm really lucky in that I don't take any, but if my doctor had her way I'd be taking at least 6 different types of pills a day for the rest of my life. I found that simple changes in my lifestyle and diet would eliminate the need for what I've been prescribed so far, but I know that it doesn't work for people with serious health problems. Nowadays many people get their prescriptions from Canada or Mexico to save money.
I don't know what the "anything else" is, but if you check out
http://www.freecycle.org you might find that somebody in your area is giving it away. Also, many areas have organizations for people who are willing to barter the goods or services they can provide, for what others have that they need. If there isn't a barter group or a food buying cooperative in your area, you might think of starting one.
Credit cards are almost a black hole, but not quite. It is possible to get out of debt. On the other hand, I've found that they can be addictive, and that it is easier to get out of debt than to stay out of debt. Good luck!

2nd edit: OVERDRAWN? I once knew a couple who were spending more on overdraft fees every month than my entire monthly income. I suggested that if they wanted to throw money away, they were welcome to throw it my way. They soon found ways to avoid being overdrawn. The problem was that they had seperate checkbooks and debit cards, and didn't always know if the other had written a check or used the debit card. After my comment, they got in the habit of phoning each other before making a purchase or payment, to see if the balance in their checkbook was up to date.
