Yup. Breathe, get enough sleep, and move forward. Small lists help. Whatever method works (starting with cupboards or a small room, rearranging the house by subject, ruthlessly sorting for a garage sale, etc.) when you can cross something off the list, you'll feel good.

I have a staging area for my eBay work so after I've researched the item I can photograph, package, weigh, and have it ready to go. I leave the box open with a slip of paper that gives the item info, so once it sells on eBay I can double check the listing and be sure I'm shipping the correct item. The post office has a lot of free boxes for priority shipping, and you may find good cardboard boxes in recycle bins at places like schools or libraries, if you ask.

Make the house look the way you imagine it can look.

I have some running around to do today, and happily it is a sunny day out. Not warm, but at least a bright day for a good mood.
