Budgeting tips when income drops - what worked for you?

We are a household of 18 and the budget no longer works. It has been weighing on me all week. I listed needs and wants and cut a few subscriptions. Any apps or methods?

Sell things you do not use. I made about $750 from a weekend of listing.
