I'm not sure there is much to say about it? Just like it says on the tin, it's a suicide bereavement forum for people who loved the departed very dearly.
It's a little bit hard for me to read, as a suicidal person, honestly. But if you are genuinely deciding to CTB, you are going to have to come to terms with the fact that anyone in your life who loved or cared about you will probably have a rough time for a while, and, while they may move on eventually, they might never feel completely whole again.
We might criticize some of them for mentioning how "they had no idea," and asking "where were the signs," but I would strongly hesitate to do that when so many of us here are purposefully concealing any signs of suicidality from our family, including myself.
