There is a self-hating "inner critic" that sometimes goes into action the moment I leave, criticizing me viciously for whatever it was I talked about, and that makes me afraid of leaving sometimes. My T also told me that separation anxiety exists in adults and particularly if they have suffered past traumas. It is embarrassing to cry for no other reason than that the session is coming to an end, but that happens to me often. I usually feel a lot more normal and adult once I get into my car.
