Suzzie,
I have had a hard time keeping grounded in sessions myself. My t knows when this is happening and he gently but persistently brings me back to the room. Do you think it is possible to discuss this with your t and maybe you two could work on figuring out your cues when you are checking out and she could help guide you back to the present. Another idea would be to take 5 to 10 minutes at the end of your session to summarize what you talked about. Then you might be able to take it with you. Good luck with this.
