Sunrise,
I can definitely see how reading these correspondences would be upsetting. Especially having read some of your other posts where you indicate how great and personal your relationship with your T is. One thing that struck me most about your post was your interpretation of the "This client believes...." reference in the emails. I can see how you would feel objectified by being referred to in this manner and not by your name. I work in an allied health field where we are constantly writing various medical documents. In my area we are trained to write these notes in objective, factual ways. Most of the medical documents I write list the patient's name and identification number at the top of the record. From that point on more generic terms are used. Pt. is a 25 yr old female who c/o right lateral ankle pain.... Often the standards for these records are ..skip the embellishments, feeling, empathy..etc and present in an accurate and concise way the relevant facts. Regardless of whether your T genuinely thinks of you in a more holistic human way, when writing about you he likely slips in to standard medical documentation mode.

Another thing to consider is that email is not a secure way to exchange personal/medical information. Knowing what I know about computer technology, I don't put anything in an email message that I wouldn't leave on my desk. There are so many ways others can gain access to this information. The fact that it was inadvertently sent to you is one case in point. By him referring to simply as "the client" throughout the message might be a good thing. He might have been protecting your privacy .

In the end the relationship that you and your T have is between you and him. Your medical record and these emails are not intended to capture this. Their purpose is to exchange the basic facts only. The others in the group don't need to know the finer details of this relationship. In some ways by sticking to the factual information and only referring to you as "the client" he might have actually shown you he actually cares about protecting you.

I hope you continue to talk openly with him. It sounds by your posts you two have a good connection.
