I understand your frustration. i wonder if your T meant what she said in the same way as my T did.

My T said something similar to me. She said that she understands why I'd want to kill myself given the life that I have had. She said that she didn't think that she herself would have been and could be strong enough. She continued that my severe depression is an understandable, even rational, response to the pain but that if I were to consider that the future likely holds less pain, my desire to kill myself to prevent future pain is not a rational one.

I haven't read your previous interactions with your T. But I imagine that your T is just trying to be empathic. She wants to recognize and validate your pain and let you know she gets you and wants to support you.

What did you T say after that statement?
