Oh Marie, that must have been so hard. My mother in law had a heart attack and was found dead in her home last week. She was an alcoholic, also a product of an alcoholic upbringing and she lived a sad, resentful life. I'm so sorry for your neighbor's as their story is so sad.
I think there are times when we can't always have an answer. That lump in the throat is something that always brings me to my knees. It reminds me that I have to turn it over to my Higher Power. I know I want the answers and I want them now. Praying for you and lifting you up today as you search your heart and take some time for you.
