Oh I'm so sorry for your loss. Everyone here has offered great suggestions. Just take baby steps, maybe a few minutes each day for now.
When my Mother passed away (who always had a needle, thread and a quilt block in her hand) I had to go in and pack up her items. It was over whelming but with family and friends I got through it. I've slowly unpacked the boxes over the years and now, 6 years later, it gives me great comfort to come across something she had made or was in the process of making.
Big hugs from SC
