Simple budget for a tight month after 8 years as a procurement assistant

We are a household of 8 and the budget no longer works. I have read a lot of threads here and could not find my exact situation. The rent is fixed and the car payment is high. What helped you?

Check for energy assistance programmes. I got a credit that covered two bills.

I called each lender and asked for a hardship plan. Two agreed to lower payments for a few months.
