She must have been in great emotional pain to do such a thing. She's the reason we need to be ever mindful of the pain and struggles those very near to us may be going through. There's just not enough kindness and grace these days so we need to step it up that much more for the sake of those who are hurting enough to want to end it all.
I will pray for her daughter tonight that she will be cared for and protected as best as can be done under the circumstances and that God would put people in her path, as she grows, who will help her heal. Sorry Mason for your loss.
