A couple of suggestions: Ask your therapist if she is open to hugs. If yes, it's a great way to end the session.

To come back to the room I use the 5 things that I see, 5 things that I hear, 5 things that I feel technique. You start with 5 things, then you go to 4,3 all the way to 1. - Describing what you see in the room, what you hear in the room and sensations you feel (even if you need to touch an object to describe how it feels.

Hope it helps.
