He told me that he felt under a lot of pressure when I emailed him, because he knew I'd be waiting for a response which he couldn't always give soon after he received my emails. (A couple of times I sent an email asking if he had received an email I'd sent as I hadn't received a reply. I can't remember how many days I waited before I sent the second ones, but I didn't expect a reply straight away.)

Several times he told me he felt frustrated with me. (I can't remember the details.)

He misinterpreted an email I sent to him and told me that it "got his back up".

He once told me in an annoyed manner, while he was speaking to me in a particular session that he felt like he was the client, rather than the therapist.

In our last session (which neither of us knew would be my last), he said he felt like he was "crawling his way back up", once again in an annoyed manner, while we were discussing the reply he sent to the email that he misinterpreted.

During this last session he could see that I wasn't feeling very happy and asked me why. When I told him that one of the reasons was because he was obviously angry while talking about the email he misinterpreted, he became angry again and literally threw his hands up in the air.
