Simple budget for a tight month - 16 weeks in

We are a household of 4 and the budget no longer works. Thank you in advance. The rent is fixed and the car payment is high. Any apps or methods?

Keep everything in writing and save the confirmation numbers. It saved me later.

Thanks for writing this out. I went through something close to it 6 months ago, and it got easier once I kept a simple log of every call and form.
