Need an intervention...

I am so overwhelmed with my house that I get discouraged and stop clearing out stuff. HELP!? I have several friends that have already offered to help me but I don't know where to start. My biggest problem is where to put things temporarily while I sort through stuff. The biggest starting point is Steve's office. I get a real energy and start working at it then wham; memories just start making it impossible to finish. Oh how I miss him...
