Not much consolation; her life ended suddenly. My greatest fear is a lingering death. Alzheimers, Parkinsons, Stroke, anything where a person loses all dignity, deteriorates slowly over a number of years. No one mourns these people, survivors feel relief. You have happy memories, they aren't overly contaminated by years of unhappiness. I know you had your own painful time, she was there for you, this is a happy memory. Hang on tight to happy memories! They get you through the days ahead.
