I was in exactly the same situation as you this time last year, sinking fast and paying all my bills with credit cards, I am now in an IVA and at least now I can see light at the end of the tunnel.
This Forum is great for advice and 'Welsh Boy' has given you the first good bit of advice, seek professional help, also use this Forum for advice, you wouldn't believe the number of people in the same situation as you, the knowledge base for debt related issues is massive.
You have taken the first step to a solution by admitting you have a problem, contact Melanie and I know she will give you the best possible advice.
You aren't alone, good luck and keep posting
IVA COMPLETED ON THE 17th MARCH, FINAL I&E COMPLETED 26th APRIL, COMPLETION CERTIFICATE ARRIVED 2nd AUGUST
