I am confident you will find your Mom's jewelry box, but in the meantime, remind yourself that your Mom isn't attached to the jewelry. She lives on in your heart. I'm also sure she would forgive you if the box is gone. I realized something after my Mom died and my sisters cleared out her house without involving me, even though I was in the will. There is never enough for my siblings. I have nothing--not even a picture. But a few months after her passing, I know my Mom was in my house. I know it because my dog saw her. I felt comfort after her brief visit. I believe she came to reassure me that she was aware of the situation. I never felt her presence again after that day, but your Mom also knows your situation and the rush you were in. Jewelry items are just things. Yes--it's nice to have things that remind us of the person we lost, but in the whole scheme of things, they are just "things" that you can't take with you after you are gone. I'm still confident that you are going to find the box, but your Mom lives in your heart no matter what. I'm sorry for your loss.
