you seem to have serious financial problems, but most problems can be solved and in fact, the new buzz word, it that you do not have problems, but oppertunities and challanges!
You need to drastically reduce your outgoings, to at least balance income and ideally, generate a surplus.
Could your lender agree to an interest only repayment for a period - perhaps 6 months.
Can petrol bills be reduced? can you walk/cycle/public transport to local shop/work/school? Do you need the car you have - can you downsize the car or if you have two cars, do you need two? Could you operate with one?
As regards food, can you reduce costs by buying cheaper food? This does not mean poorer quality, oft times it can actually be better quality, but you need to do the work in preparing and cooking.
For example - 20 chicken wings cost €2. these can be roasted and eaten straight form the oven, can be boiled then deboned and made into curry/stirfry. All far cheaper than the cheapest takeaway.
Can childminding expense be turned into an income? Coulr you/hubby mind the hildren and possibly take inanother 1 or 2 children?
Could you rent a room in your current house. it is a dimunition of privacy, but hang the pride - your life and what yourworked for and dreamed of is at stake. Again, it need only be short term.
If you could get your debts/income in order, then in 6 months, you would have a much better chance of getting a loan from a standard lender at the standard rate.
all is not lost, but your future is in your hands - only you can take charge and take control.
