Today we buried a friend of our family who took her own life. We are in another city, far away, so we couldn't attend the funeral. Question: How do people mourn at home in such cases? Can we do it during dinner? This is the first time in my life I've faced such a situation. No one knows what to do, what to say, or what to think... My mother is going through an incredibly hard time; she's been crying all these days. She can't even pray for them (please don't comment on this!), because they told her that no one prays for them. I've prepared dinner, and we're going now. How should one generally behave in a situation like this?
