Hi bassetlaw and welcome to the forum
Have you consulted an insolvency practitioner yet? If not, then this might be a good idea as they ought to be able to give you lots of advice as to the options available, which may help take away those apprehensive thoughts.
With regard to banking facilities, if you currently bank with a lender to whom you owe money, you will need to find alternative arrangements. I hear that the Co-operative Bank are very good in this regard.
