Have you read Mari Kondo's book The Life-Changing Magic of Tidying Up? I haven't been able to implement it, but I love some of her ideas about how to reconceptualize tidying and how we even think about and relate to our stuff. I recommend it—even if it ends up not working for you, you might get some good ideas!

Great work on getting so much stuff out, and good luck in your continuing decluttering adventure. <3
