I am so sorry for what your family is going through. Suicide is a horrible thing. It happened in my family and I know how everyone involved is suffering. My prayers will be ascending for God's mercy and love for all.
I am so sorry to hear about the suicide attempt, especially by hanging. My father "succeeded" with his hanging, so I know it can be traumatic. May God embrace all who were involved. Take good care of yourself.
This is a very difficult, emotional and complicated issue. I undertand this from experience as I myself as depressed and have been suicidal in my life. It can be heart wrenching for the families as well to bear this pain. My prayers are with you and your family
