I don't have a plan or any guidelines in place for myself but I can relate to having indecisive family members who freeze up in emergency situations. There have been times when I really should have been hospitalized but wasn't because family didn't know what to do or didn't believe I was bad enough to be hospitalized.

Times when I have been hospitalized were when I was feeling urgently suicidal or homicidal, feeling out of control and not trusting myself to make good decisions, having severe hallucinations. I would be interested to know what would constitute the need for hospitalization when depressed as I have always been IP when manic or mixed.
