Thank you everyone for the ideas and advice. Sometimes it's good to just spill the beans by putting it all down in writing. And yes, I did do the look in the mirror, and said "Who in the heck are you, anyway!!!" It was cathartic.
So, I'm approaching this now from a different direction. When you change from house to condo or to motorhome, it's like opening the door to a friendly space. You remember happy times, familiar furniture, a cozy place where you love to be. So instead of dragging in bags of stuff, look forward to all the treasures you left at the place where you're now headed, to be enjoyed anew. A change in place gives a fresh perspective, so relax and breathe.
That said, I did decide on a few projects to take along, but with the spirit of bringing some new friends to join the party. And my binder full of new patterns. Well, they won't take up much space and can travel back and forth.
