['I was devastated when my aunt died alone. She had a heart attack and no one was there for her.', "I'm so sorry, how sad.  Do you wish you had been with her to say goodbye.", 'I really do. I used to go to her house a lot, and I could have been there then too.']
Of course I can understand it, but at least she probably didn't suffer and is now in heaven.
When I found out my aunt had a heart attack and died alone, it devastated me. I was not sure what to do with myself afterwards.
