Don't waste time worrying get some advice! (CAB)
And tell them eveything they need to know, no point being embarrassed and hiding a few lesser debts
If you get called to court - GO - judges are very sympathetic to people in debt
CAB if possible first as they may go with you to plead your case

Remember Baliffs are employed by the courts so you would have to have been summoned to court before there could be any mention of baliffs. So if you get called to court, go, be early, try not to worry and just put your case
as Morticia said why not join Mudcat, its free, and that way you can send personal messages (PM) to the people here instead of putting sensative information on public view
Go and see a CAB adviser now
