Most T's have a plan & rules. All mine have always laid them out in advance. One gave certain *actions* that she felt would require her to hospitalize. Current one will not call the police, literally or figuratively. He will however call the hospital, prepare the way, let them know what's going on, & accompany me should I decided safety requires it. We've even decided on a hospital where he can continue seeing me. We also set up conditions under which I agree to call him. Never needed to put plan into action. But I feel more comfortable knowing exactly what to expect from my T. What he expects from me. Like also knowing the decision will remain mine. Think it may also make it easier to talk with him about related issues.
