Psychotic Depression. It's a whole 'nother animal. I was depressed and psychotic when I drove headfirst into a tree at 60mph. There is absolutely nothing rational about a state of mind when experiencing this. Not one thing. My pdoc said to me "next time let us know". I thought he, of all people, would know that a psychotic mind wouldn't be rational enough to recognize how skewed/irrrational its' thought patterns were. Is suicide selfish? Not in every case.
