Right, but isn't it about coping with that response, not eliminating it? That was the impression I had of what it is. The goal isn't to eliminate sadness or anxiety, but to limit the negative impact it has on your life. So you don't get into these cycles were depression prevents you from moving forward, which makes you more depressed and so on. That's why it supposedly works so well with people with bpd, right? Because bpd is all about fear of people leaving you, while you behave in ways that absolutely ensure that people will.
