OOOO We all tend to have "session withdrawal" I think? We go to a safe place (T's office) and share and then have to come back out to daily living!
I would ask the T to give you more time at end of session to acclimate back to dialy life. This might mean 5 or 10 minutes before the end of session that T stops the "therapy" part and moves to current what's up for the rest of the day for you, what the weather is doing etc.
IMO it's always difficult for a T to stop a session that is going well with therapeutic interactions, but sometimes they need to be reminded, esp if you are having such a big fallout afterwards.
