Hi Sarahw and welcome to the forum
You can petition for your own bankruptcies in your local County Court - this will cost approximately £500 each, and will bring an end to your financial difficulties providing that you do not own any assets.
You could also consider entering into a Debt Management Programme if you have sufficient disposable income to make ongoing payments to your creditors. I would only recommend this to you if you have assets to protect under bankruptcy proceedings.
