["My mother's husband had alzheimers and went downhill really fast after the diagnosis.", "Im so sorry to hear that. She must've been devastated.", "He passed away about 8 months ago and she's not doing well with it at all."]
I am so sorry to hear that. She might be hard to be around, but I hope you spend some time with her.
