First, I am so very sorry to hear about your dog. I know how hard that is, and I'm dreading the day when I have to let one of mine go.

Second - I do think you have cause to be upset. I think there's a big difference between wanting to be the center of the universe and a reasonable expectation that your T will remember things from one session to the next, or will remember things said in an email or phone call. I do not think it is at all unreasonable to expect T to remember things you've discussed. If they can't remember, then they should be taking notes and reviewing those notes prior to your session. How can you expect to make progress forward when you have to keep retracing steps to jog T's memory, or remind him of the things that are important to you. Working with a T is hard enough as it is...he shouldn't be making it harder on you by needing you to remind him of what's going on with you and what's important to you.

It's probably not that T thinks you're unimportant, it's probably just that he has a crappy memory. Perhaps if you point out that you find it distressing that he doesn't seem to remember things you've told him, he will take steps to rectify that. You could even say that you don't mind if he takes notes during session if it will help him remember and you don't mind if he reviews notes at the beginning of a session. Maybe that will give him a hint that it's very important to you, and you've even given him a way to help solve the problem by suggesting taking notes.
