In your situation, there's nothing wrong with going to a food bank so that you're eating more than PB sandwiches.

Have you sat down and looked at where your money has gone over the last few months? You need to do that before you can fix the problem. Don't lump things together. List all your utilities separately. List all your monthly subscriptions separately. Separate out food and restaurants.

And yes, it sounds like you need a higher paying job. Hopefully, finding one will be easier after the first of the year when budgets reset and the holiday chaos is over. You might also consider a second job for the evenings and/or weekends as a short term partial solution to your cash flow issue. You have a house. Renting out a room or two would also be a huge help.
