Bill always loved to move so we did - a lot! And my job was to always handle everything.
Your idea of decluttering is a great one. On moves I always started early on the sorting, decluttering, etc. I would set up a throw away box; a charity box; a pet toy box for Humane society; a box for things that needed shredding, a box for keepsakes kids might want, etc.
Then I would take one drawer at a time, usually while listening to music or watching TV, and sort through it. I took my time. Then, when it actually became crunch time for moving I just needed to pack things, which would go pretty quickly. Anything I knew I wouldn't need before hand I would pack and store.
Whatever you can do to relieve your stress is a good thing. You actually do best for everyone by basically putting yourself first. Best wishes.
Thank you, Julie.
