Lord God, I ask you to protect Mr. Anderson from absorbing her pain and anguish. Give him your peace that passes all human understanding. Let him and all her family grieve for her normally and not take any responsibility for her tragic decision, in Jesus' name.
@Lisa thank you; @TempestOfTempo thank you; @JoChris not to take responsability will be a really difficult thing... While all my family did everything to help her I'm afraid that her parents took the hit harder than the rest of us. I'm more worried about her soul right now. I've been praying for God to take her soul from wherever it is now.
And very understandable too why her parents would feel that grief the most.
People can only do so much - even the best possible psychiatric care for suicidal patients isn't guaranteed 100%. If someone is determined to kill themselves they eventually find a way. I'm being objective there, but that's no comfort for you and your family of course right now.
