If I were speaking to someone who had lost their child to suicide--first of all, the sadness, anger, regret, those things are very common feelings. It happens to everybody. Everyone involved will start wondering, "What could I have done differently? How could I have done it? And if I had done this, then something different would have happened." What I want to say is that this is not your fault. This is not an indictment of your parenting. Saying things like "How could my child have done this?" is also not very helpful because even you, as the loving parent, don't know enough to judge, and that judging is a completely unhelpful thing. Leave that to God. I think that the right things are to know that your child, now in the spirit world, can progress. I believe, the vast majority of cases, we'll find that these individuals have lived heroic lives and that that suicide will not be a defining characteristic of their eternities. And to the extent that he trusts the Savior, he will be healed. You too have the ability to trust the Savior, and you too will be healed.
