I have felt like this sometimes. I find washing baskets awesome.

I bought heaps! LOL! I often walk around the house with a washing basket and collect the clutter that seems to get eft everywhere and then sort it out. Sometimes if I dont have time or energy to sort it, I just put the washing basket full of stuff somewhere and at least all the clutter is in one place. I know it is only temporary solution but it helps me.
I second the washing basket - I throw random things in and put them away when I have 5 seconds... Although sometimes it takes a few days!
Another thread a while ago suggested you leave a basket in each room for a week and add things to it you don't actually use or take up space and cause clutter. At the end of the week be strong and throw the contents out. I did that and got rid of silly things on my bookshelf & random toys that were broken, not part of anything... I felt good! Looking around now I may need to do this again.
I have baskets then get frustrated because I have to put it all away LOL
