Sell Everything You Can.
It's better to sell everything you own than it is to go into bankruptcy. Move to a smaller house. Sell your cars and take the bus. Take a good, hard look at your life, and realize that there are very few true 'basics': you can do without almost everything. Your house is probably full of quite valuable things that you never use, so bite the bullet and get rid of them. In short, subtract your debt payments from your income, and live like someone who earns that much.
You are going to lose almost everything you own if you declare bankruptcy, so you might as well try to sell it yourself at a better price and avoid the bankruptcy issue altogether.
If you can get extra hours, do it. Being bankrupt is such an indignity that you should at least try going to your boss and asking for a pay rise or promotion. After all, the worst they can do is say no. They're going to find out about it anyway if you declare bankruptcy, and they might wonder why you didn't come and ask for their help. Also, if you're married and only one of you works, try to get the other a job - you never know, it might even be fun!
Use the Power of Threats.
One of the best things to do when you're considering bankruptcy is to write a letter to absolutely everyone you owe money to, letting them know. Make it a very clear threat: "if I cannot find a way of paying my debts then I will be forced to file for bankruptcy". Most creditors would rather let you pay back a tiny fraction of what you owe than have to try to get money out of a bankrupt.
Know Your Local Laws.
Bankruptcy laws vary enormously depending on where you are. There are some places where you'll be forced to give up everything you own to pay your creditors, some places where you at least get to keep your house, and some where you can declare yourself bankrupt and not even notice! Try to get a lawyer - you might think that you can't afford one, but many will work 'pro bono' (for free) for people who really need a lawyer but can't pay.
If you still cannot see the light at the end of the tunnel or if you are just looking for some advice on how to best remedy your situation you make want to seek out credit counseling.
