I almost did with T, when we had the session talking about his reaction to my holding the stone (transitional object). At one point, I was just like, "Maybe I should just leave." Because I just felt there was no getting through the impasse and talking seemed to make it worse. And I felt hurt and shamed. But I stayed. And I'm glad I did. (Because I pay at the end, I also wasn't sure how that would work. If I was just like, "OK, I'm leaving," would he have said, "Wait, you need to pay first!" Which would have been tremendously awkward. In reality, I imagine he'd just send me an invoice. But not being sure contributed a bit to my not leaving.)
