Rent a storage garage (climate controlled), then put all your non-vital stuff into it. If it isn't worth storing you can throw it away - right away.
If its something you think you should have used during the year (not long term keep sake or legal documents), then figure out what your going to do with it. Don't do everything at once. Just pick some stuff out of storage and determine what to do. Slowly.
If you need it, just grab it from storage. If nothing else, a storage garage makes a fine place to keep your encrypted, backups.
[edit] put Rubbermaid shelves (or equiv) in the storage garage, do not pile boxes. That will defeat the purpose. The Rubbermaid shelves are easy to put up and sell / donate later.
