Jackie,
Thanks for your response. Indeed, it does seem that you have had an awful year, and I am sorry to hear of your losses and unadulterated bad luck. This is one of the very few cases that merits individual investigation.
Firstly, I would go to your branch and ask for a one to one interview with a manager or senior clerk. This has a couple of benefits that spring to my immediate attention. Primarily, you will have their undivided attention. Secondly, you will be in a separate interview room (hoepfully) where you will be able to have some privacy.
The bank ought to handle your claim sensitively and sympathetically. Do you have any other creditors aside from your bank (credit cards, loans, HP agreements etc)? They may be able to temporarily suspend your payments which would mean that there would be less strain on your bank account whilst you get back onto your feet. If you do this BEFORE the interview, the bank will realise that you are taking this matter seriously and will invariably look upon your request more positively. I would urge you to be honest, open and let the bank know of your full situation. The more information us bankers have to hand, the more we are able to assist the customers. Help us to help you.
If you are able to place a forward plan to them which helps you and the bank alike, then they would be fools not to take you seriously. At the end of the day, they want any money owed to them paid back; and if that means giving a little leeway then so be it.
Communication is paramount. If you need assistance on contacting your creditors and suggesting a reduced repayment plan, then your local Citizen's Advice Bureau will be pleased to assist.

Good luck, and I am sure that with some perseverance a positive ending will be in sight.
