Thank you for clarifying the situation regarding your business gillybob. What a shame that it wouldn't be possible to get help, but as it is such a specialised field I can see how that wouldn't work in your case.
I do however think it's worth you contacting the bank to explain your situation. You did say they wouldn't stop any direct debits and standing orders which is reassuring, but would it not be worth asking if they would possibly consider reducing, or even waiving the interest payments, at least for a limited period?
Financial sections of newspapers are always urging folk in your situation to contact their bank/building society and explain the situation. You would need to speak to someone with the authority to do something, but they would have heard similar stories before and are often sympathetic apparently.
It's certainly worth a try I would have thought.
