I also never had a problem when my therapist went on vacation, other than simply missing him and looking forward to his return.

I have no doubt that therapists care for their clients, but I really doubt that my T ever would have felt abandoned by me. He did say, though, in response to my telling him that I would miss him when I left therapy, that he'd miss me too. He always came across as a very happy and well-adjusted type of guy. I honestly think he felt happy for me that I was moving on in the world. And maybe content in knowing that he had done his job well and could let me out of the nest, so to speak.
