I agree - not pathetic! I keep in contact with my old T, and I know two other clients of hers (my friends ) who do as well. I love keeping in contact with her, and I know she enjoys it too. My friends occaisionally go out for lunch with her, and since I now live in a different city I just keep in contact by email and the odd phone call.
Both my friends and I were long term clients of hers, and she supported each one of us from a place of hopelessness, misery and helplessness to a place of emotional and mental health (the latter more so for my friends, but I'm getting there).
Having no contact at all with someone who played such an enormous part in my life would just be plain wrong!
