Mary,
This is sorrowful news. Debbie was one of the people I enjoyed talking to most on this site. She and I shared a lot of similar frustrations. More importantly though, she and I shared similar passions for the "finer" things in life (mostly our snacking preferences!)
My heart goes out to you. Our prayers are with you as you grieve. We grieve with you. Another bright light has gone out, and the world is a bit darker for it.
In Deepest Sympathy,
Lauren
