I am feeling your pain. I have been in the same frame of mind and heartsore also. This month it was one year ago My Mama died. We had her at home with us and had spent the last two years with her as she needed care. She was a joy and my heart has a hole that sometimes I wonder if it will ever heal. So, I will keep you in my prayers, and am sending hugs. Your quilt is beautiful and I am sure your Mom would be proud of you.
Sorry for your loss. In my experience the "hole" never heals but the pain lessens with time.
