This wasn't unexpected. 81 years old. Please pray for her soul. And for my sister, who must deal with "closing up home" (same Midwestern city / separate residences). Thank you (I'm okay).
There are no words to describe such an event but I will pray about it. I am so sorry. We had to go through this 2 summers ago.
Sincere condolences, I will pray for your mom, your sister and yourself. Take care of yourself, it is a hard time.
