Bankruptcy should be your very very last option, it is not the panacea that some may have given you the impression that it is.
Don't try and get a bigger loan or overdraft facility to cover the outstanding debt, and for God's sake do not put your affairs in the hands of a debt management company - all you'll get is 7 years of penuary and they will make a huge amount of cash from you.
I am not being patronising, I've seen this situaton at very close quarters before, clearly you can't manage your financial affairs, you need advice from people who have your interests at heart no the profit margin involved.
Go bankrupt and you will lose everything - house, credit rating and normal banking facilities. You will be assigned to a court appointed bankruptcy officer/iquidator, who will rule your financial life with a rod of iron. All your earnings will be assigned to them, they will then decide how much you will need to live on, the rest goes to the people you owe money to. This will continue until either your creditors give up, or you repay them in full - neither is a quick or realistic fix.
Take the advice given, go to your local CAB, look inthe Yellow Pages under debt, but do something now , because you haven't got much time.
