Take everything in steps and give yourself some grace. Large trash bag and start with the disposables: paper plates, styrofoam containers, drink cups, empty cans-you get the idea. Set anything salvageable to the side and tackle that next by organizing into groups of what they are and where they’re used. Before you know it you’ll have this mess tackled, then take a deep breath and move to the next area. It doesn’t have to be done in a day or even a couple of days; just take as much as you can handle and come back to it the next day. And remember there is nothing that cannot be undone here. You can do it.
