Mine is a mess too. I don't like the cupboards I have because I have to get on my knees to open the doors. The house roof slants w/no dormers, so I cannot put bookcases flat against the wall. It's a combo storage room & sewing room. Lately I've been purging the storage portion. LOL
Flylady.com says we can do anything for 15 minutes! When I get overwhelmed, I set my timer & work on cleaning til it dings. Then I leave & shut the door!
