At my last goodbye my therapist and I sort of wrote a plan for any new therapist I might have, things that I need to work on and then we hugged goodbye and then I gave her the card and gift I got her. i didn't watch her open it because I was afraid she wouldn't like it. I don't suggest you do that because I was wondering if she liked it and end up calling her to find out. Expect to feel emotional and sad. I was extremely sad. It is hard for me saying goodbye. Try to leave nothing unsaid.
I will be thinking of you when you have your last appointment. I know how hard it is leaving a long-term T relationship.
