My bedroom is so disorganized?

I usually keep my room very clean but lately I've been so busy I get lazy when I have time off. I end up throwing laundry in a pil on my floor, my desk is stacked with papers and my bookshelf is overstuffed. I got a new set of furniture recently and its a lot bigger than my old set was. I had to get rid of my vanity so now I have a hard time finding homes for little things like my makeup, extra college supplies (pens, paper), textbooks, etc. Any storage solutions/suggestions?
