This is true. When I was younger my fiancee shot and killed himself, not suicide, but an accident, and it destroyed me. I didn't eat for two weeks, I almost died myself. I STILL cry when I think about him and it has been 10 years now. And my mother is schizophrenic and has attempted and talked about suicide many times. It really is a destroyer of the soul. Please, PLEASE be sure his daughter seeks counselling of some kind immediately. And perhaps your mother should, too. It is very difficult not to partially blame yourself for things like this. My prayers are with your mother, and all of you. I'm so sorry you have to go through this.
