Almost bankrupt... But need to borrow again

Thanks for the responses so far.
"Private medical" was my way of not having to get into details, but considering the less than helpful remark about it, i'll let you know that the borrowing was to fund IVF treatment due to the NHS refusing to help. Apparently if your partner already has a child, then you are not allowed funding because you should be 'happy enough' to have one child in the house already.
As for needing to put the children in the car. We have three already, as the above resulted in twins. We are due another in 6 months, which means we need a car big enough to fit 4 children's car seats. It's quite a simple request really, to want to be able to physically take my whole family out without having to take two cars...especially for school runs or emergencies.

The long and short of it, is that would it still be 'fraud' if I cancelled my bankruptcy application before I file and just continue to borrow. In effect, it's no different to just carrying on digging a deeper hole. It's not ideal, but I just don't see any other option at the moment.

Well it's nice to see there's a strong holier than thou attitude on here. Apologies to the few who replied with neutral comments but the majority of responses have been appalling.
I spent my credit trying to start a family, and a small amount partially funded a wedding. I lived completely within my means, haven't bought anything lavish and made every payment on time. We haven't had holidays for years, we live frugally and just scrape by. Finding out we're having another child has meant we have to move house, there was no other option. Cost of living and housing is so expensive to the point that what was affordable, now isn't.
This is not a get out of jail free card. This is something I have actively avoided and done everything possible to stop happening. I have tried consolidating existing debts to make them manageable, but no lenders will offer anything. I have tried moving to a council property to save money, but my local council won't even speak to me as I am not old or disabled as that is their priority.
I have actively avoided any additional borrowing for the last few months. I have tried to work within the rules of what is ok but my already cheap car breaking down weeks before filing has meant I now have to extend borrowing to buy another cheap car.
I have looked into hiring cars but it is too expensive and is technically another line of credit. I need a car to get to work (35 miles away) or I'd lose my job. My wife needs a car to do the school run as the closest school is nearly 4 miles away. Or should a pregnant woman be forced to walk eight miles, twice a day?
I understand my original post may have left out details as I was looking for quick advice in case there was anything I had missed or could do instead. However the responses are wholely unjustified to the point I will not visit this forum again.
Maybe you should think back to when you took borrowing and whether you spent every penny on something other people would class as 'essential'. Keep your opinions to yourself, they don't help anyone, especially when people are obviously in difficult and potentially upsetting situations already.
