Lori so sorry about your neighbor. I too had a neighbor that did that. He just couldn't handle having cancer. I even saw him laying in the yard after he shot himself in the head. So very sad. Many years ago I had a cousin that wanted out of a marriage. He felt the only way to do that was to commit suicide. That is the worst. He was like a brother to me. I still think about him daily. Yes, the family and friends left behind suffer and it is hard to understand. Take care. Praying for his family, especially his grand children.
