Goodbye, my Sam

I'm beyond heartbroken.  My Samantha passed away last week.  It was very unexpected and sudden.  She was here one day and gone the next.  For that I am very grateful.  I would not have wanted her to suffer.  We still don't know the cause as she slipped away so fast and at that point extensive testing would have caused her undue discomfort.  She was such a sweet and loving girl, who gave us so much joy in her 12 years with us.  I know she felt loved everyday.
