I go through files, keeping only the necessary papers.
Double checking clothes and shoes; seeing what fits, deciding what should be taken now and what can wait. Tossing anything not worth mending or that seems to have gone out of style.
Hanging on to the things that have value of some sort, and making trips to the dumpster to discard the things I've held onto without knowing why.
Organizing the things I know I'll want at some point, but can't deal with right now.
I'm overwhelmed, and it's not really the boxes. It's what comes next. It's the worry about getting where I'm going. The doubt that comes with change.
