How have you said thank you/goodbye to your long term therapist? (With an ending you agreed to)

[Charbella]

It's hard trying to find the words to put in a 'card'/email. As I want the thank you to be about her, her skills, her work. Her.
But everything I write, it leads back to me, and then I am putting me back into the thank you.

Could you do a word collage? Just start writing words that express you gratitude and then plug them into a computer and put therapist or someone in the center.
