I think if you are high risk and calling your T right before planning to commit, s/he would be calling 9-1-1 from another phone line. Ethically, I believe s/he has to anyway. I can't imagine a T. (or anyone) taking a chance at losing someone, especially since they know how haunting that will be to them for the rest of their life.

I'm glad you are still with us, Ad Intra!
