I don't think T predicted your reaction and I do think she wanted to help you feel better before you left. None of this has escaped her attention and you can go back to this any time and any number of times.

I completely agree that next session should begin with talking about this one. That's how many of my sessions go. I will not say something in session (because I am working on being in the moment, feeling my feelings then and there rather than the overwhelming rush after I leave, or when I get home, or even the next day like happened today) but I will start the next session saying what I wanted to in the previous one.

It sounds like you did give yourself permission to feel and cry and it helped. It felt good that you responded in the way you were wanting to. It happened right at the end, and the end and leaving/separating can be so hard already.
