You can inoculate yourself against that paralysis by making a list of things, things you need to do, but ALSO things you do everyday, so you can see what it is you're doing.

Work through the list and cross off things at every opportunity as you finish stuff. And establish a beach head somewhere in the house, where you can empty it out and put back just what the space needs.

Bathrooms and laundry rooms are good places to start, usually because they're so small (in contrast to closets, that are even smaller, but are usually packed full and their contents tend to explode into a room, making matters appear worse).

Good luck!
