@emiedecastro For me, I would really consider the faith and the belief system of the person before saying anything God-related. I totally agree with what you said about encouraging medical/professional advice though! And I'd add, we need to listen - really listen - to our friend and try to look at things from our friend's perspective and not our own.

@lynnchan Maybe mom is sad to see grandma's condition. In a closed tradition it is better not to ask what and why she is sad. I think mom will refuse to talk about it and is becoming more and more secretive. Just give your attention. What does she like? Cake? Have cake with her. Give her warm hugs. Long and friendly hugs. Don't ask anything, but let her cry in your shoulder if she wants. Tell happy experiences with mom and grandma. Laugh with her. Say that you love her and grandma. If mom wants to share her feelings, please listen and hug. If she doen't want to talk, don't force her. All your mother needs is a feeling of comfort. Maybe if she is asked a lot of questions, she will feel uncomfortable because she worry about giving you trouble. Just give your attention and love. Pray together and let her hear your asking for her: may God help and love her very much. Bless you and your family.
