Please, how do you “give items a home”

I’m an adult (26) living with my senior dad and stepmom with a basement bedroom (I know, don’t make fun of me, I like it here). I am in a constant unending battle with my hoard. I don’t know that I am literally holder, but that’s how I feel sometimes. My life has been nonstop with ankle deep trash, laundry, stuff, etc. Bags and boxes and piles. I guess everything is supposed to have a place but my brain just cannot comprehend that concept no matter how hard I try.

Like how the hell do people figure this out? How do you avoid just dropping shit you don’t want to deal with in the floor and forgetting about it? Because that’s so ingrained in me I genuinely don’t even recognize that I’m doing it. Or just dropping it on a table, a dresser, a desk…etc. the idea of things having somewhere to “go” baffles me. Yes I get some things are generally the same. Clothes go in a dresser or get hung up (but I hate dealing with either), other than that I’m at a loss. I’ve tried baskets and boxes, it has not helped.
