I still can't catch up

so yesterday..well actually two weeks ago i was supposed to make the mortgage payment. me and hubby get paid every week so i have to break down all of our bills weekly. well every week there is not enough money so i have to push some things to the next week. even though we are about $50.00 dollars short for our mortgage payment considering what we have in the bank i'm just thinking of different ways to make a quick fifty bucks. On top of that I still have to put gas in my car. so in other wards i'm probably negative about 80.00 dollars...goodness gracious...at least we have food for the weekend...i guess we will just take the kids to the park or something free....
