My house is Empty but trashed

So I came home, My parents staying out of town and I’m alone at home. I was eager to invite a friend or two at my house, Then my Ex texted and maybe she will come today. Well the problem is… when I came home my room, hall and everything is not clean. It has a lot of clothes lying around, a lot of stuff that shouldn’t be outside and in the wrong place. Idk how do I clean my house!!! There is stuff in every room and no more room to Place these items anywhere. either I need to throw these or idk, Place them systematically on the floor. Its like I’m staying with garbage all around me. Its feeling cramped.
