I thank her at the end of every session as we hug. I have also thanked her in emails after a particularly hard session and a couple of times in a card that I mailed. She has at times said that I don't need to thank her. I tell her I know that I don't need to but I want to add I am thankful that she is there and safe. Granted I pay her to be there but as I have told her I don't feel like just another client.
