I think it depends on the client, the clients history and how desperate the T perceives the client . Having a plan does mean you are contemplating it, however it does not mean you are actually ever going to act on said plan. At the end of the day, you and only you are the one who knows if you are truly a danger to yourself. So if you can't trust yourself to protect you then its important to trust someone else with that information, so they can help.
