I'm big on black plastic bags

Put all the laundry in them and/or in your car(?); I had a major cleaning of my house a few months back and just took all the flotsam and jetsam and boxed/bagged it and put it in my car until they left so all the surfaces would be clear, etc.
When I moved last time (2005) I had closets full of clothes I could not deal with so I took the entire stuff, bagged to the cleaner! Yes it cost over $100 (I did sort and throw out/donate a lot) but then everything was neat, clean, on hangers and I just moved them to the car and to the new closets. Just sort the clothes for cleaning and/or throw stuff away; if you have 982 pairs of underwear, decide to trash all but 7, and that keeps the laundry down. I find throwing away ripped or dirty stuff isn't as hard as dealing with it otherwise. Just get mad at it being a problem for you and let the anger take itself out on the clothes.
