There's also a very useful paperback called "How to cope when the money runs out", by David Benedictus (ISBN: 0862417333) which you should be able to get from the business section of any goog bookshop or from Amazon.
It takes things one stage further than the advice you'll need from the CAB and will help you get your credit rating rebuilt, debts consolidated etc.
It's written by a bloke who's been at rock bottom, with input from banks, lawyers, the CAB and various other bodies - well worth a look.
