I think the term doesn't give any indication of the circumstances, tbh.
DH and I went bankrupt 11 years ago. We only had a combined debt of £16,000, and my debt was 'only' £6,000 (I say 'only' to acknowledge that I realise it was still a large debt, and one I couldn't pay, but in terms of debts, it's very small). However, we couldn't pay it, and we had taken consolidation loans to try and manage our debts and were at the end of our line. No such thing as DROs, then, and no assets.
We couldn't afford childcare, my DD was 1 year old, and my Mum, who was taking care of DD1 when I was working 30 hours per week, was clearly not managing with her (MH). The only solution was for me to stay at home with her, which I could only manage if we didn't have the debt. It was impossible.
Because DH and I had consolidated loans and debts from each other, the advice we were given was that he could be held responsible for my debts and I could be held responsible for his. The only way we could be completely clear of them all was if we both filed bankruptcy. The Judge said that although the sums were low, he saw the sense in our case and he wished us well.
As for learning our lesson, we have never had a loan, overdraft, credit card or any other credit since, despite being bombarded with offers. Our 'bottom line' is £0. That's when we run out of money. I panic if we go below £300 in the account.
