Hi Pop, welcome to our group.
I had the same problem with my T back in Sept. He had me picked up and detained in the psych ward because I wouldn't promise him that I would be alive the next day.........I had no intention of being around, so he was correct.
In terms of SI, my T can't unless it is a life-threatening matter. Otherwise he must respect the patient/doc confidentiality. I have approx. 15+ cuts on me right now and he knows that I am doing it. They are deep, but not that deep to cause irreversible harm to myself.
I felt very betrayed when my T did that to me - but upon reflection, I understand why he did it. I wish he hadn't, but I'm not angry with him anymore like I was initially. It took us awhile to get back to our "normal" relationship.
I think you should mention it when you go. I usually see mine every week, every 2 at the most. Since my brief stay in psych, it has been almost every week. Tell her so that maybe she can help you - give you some alternatives to SI. That is what mine is trying to do. He knows that until I find something else that makes me feel better, I will continue to do it.
Take care, and let me know what happens, please. I am very interested, esp. due to my case.
