For me, going to therapy dredges up so many painful emotions. It's hard to neatly stuff them all back in their box before I leave. My therapist has commented on it before. He once told me that he has trouble letting me leave because I'm so often upset when I leave. He then tried to suggest that we change how we discuss things and drop sensitive topics towards the end so I wouldn't leave like that. But that just upset me because how are you supposed to just stop talking about whatever it is when you're already there in your head and feeling whatever you're feeling. When do you stop? 5 minutes? 10 minutes before the end of session? How are you supposed to accomplish anything if you can't fully utilize your time?
