Another thing that might help is to spend a bit of time building your organization.
I believe I heard this on a Kelly podcast, that while the Book says to start with Collection for some of us it's a good idea to build at least the skeleton of an organization system early on. Processing is HARD if you have to ask, well, where would I put this for each item.
Since I'm an inveterate packrat/borderline hoarder, I totally relate to your problem. My wife has been the cure. I think clutter actually talks to her: "Denise, I'm sitting here on the table...put me away...I'm getting old and moldy...clean me up." I don't hear those piles talking at all!
My suggestion, for what it's worth, is to consider a very simple paper system to start. I'd build just a few contexts (maybe "home", "work", "errands", "computer"?) and the incredibly essential Waiting For and Someday/Maybe lists. Waiting For saves my cookies on a regular basis.
You might consider, when "digging out", making a "Home Urgent" and a "Home Later" list since you could really easily end up with 250 action items and it can be discouraging (been there done that.) Also Home Urgent gives you a place to put the "Oh my Lord I totally forgot that" items that might pop up and derail you.
Also I do like the alphabetical file system he recommends and a labeller is for some bizarre reason really cool and helpful. Why? Who knows? And for a doctor I have quite good handwriting. But the labeller helps.
It's a good trick to get a bunch of Office Depot bank boxes and number them as backlog, and put a "process box #3" etc into your lists. Warning from an experienced procrastinator: it's just as easy to procrastinate a box as a pile, maybe easier so make them "bite sized" so they don't exert a magnetic repulsion on you.
